§ 4. Internet and World Wide Web

Main topics of the paragraph:

What is the World Wide Web

The most important benefit that Internet users have received since 1993 has been the ability to work with the World Wide Web information system (abbreviated as WWW). This word can be translated as “all-worldly web.” The work of the WWW itself is of little importance, if at the beginning of this paragraph you were reminded of all sorts of information divas.

Brazil's criminal code has already suffered due to the number of current issues and the emergence of new problems resulting from new technologies. What should I do, for example, if the virus is transmitted and does not cause damage to the car, but if I use photo files for emotional value? How to classify important or virtual data?

Technological evolution has seen light evolve from analog light to digital light, a change that can be achieved with new technology. Before the marriage was transferred to digital form, the class was formed from the reader, who wrote on the back, all the jokes were collected in other books and lay in the library’s many books, the notes in the class were collected in notebooks, vikor earnest olives or pens. Nowadays, in our digital classrooms, tests can be conducted on the Internet, where you can find out the results of a large number of devices, and the notes can be compiled on computers or other electronic devices. .

It is very important to be more precise about what WWW is. This system can be compared to a great encyclopedia, pages of which are distributed by computer servers connected to the Internet. I need to get rid of it information, the buyer must go to the main page of the encyclopedia. Perhaps, bearing in mind such an analogy, the authors of WWW have abandoned the concept of a Web site.

The great change, it may be noted, lies in the fact that traditional pedagogical activity has been modified by the way of digitization of the world, similar methods such as writing on photographs or documents and research in other books. They use digital methods to better define their functions and make them more effective. .

It is clear that many parts of the world, as before, will have to adapt to digital illumination, but if they change, they may also be marked and change the dynamics of deposits, in the future it may be up to Danishly changed by them as new technologies and how we can adapt to Yogo vprovadzhennya.

Web server, Web side, Web site

A web page is the main information unit of the WWW. This will be documented as a document that is saved on the Web server. The page has its own name (similar to the page number in the encyclopedia), which you can look up for.

The information on the Web site may vary: text, baby, photograph, multimedia. Web sites also contain advertising, advanced information, scientific statistics, current news, illustrated publications, art catalogues, weather forecasts and much more. It’s easier to say: on Web sites, it’s “everything.”

Today it is impossible not to notice how the Internet and new technologies are pouring into our everyday life. This new digital world is under the influence of work, work, sports, emotions and feelings. It is clear that the digital world has brought us to greater development, since the rise has been shortened, the information may be the same as the news about the vibrations at the hour of the Boston Marathon. In addition, the work has been changed and their notes as well. The most beautiful? It’s too much to say “so”, or else to say “not”, but, of course, the trustworthiness and trustworthiness of the digital world.

A number of Web pages can be linked thematically and create a Web site. Each site has a main page, which is called the home page (Number). This is your own title page, from which you can review the documents that are saved on the server. Select your home page, place your place - name the sections. To navigate to the required section, just move the mouse pointer to the section name and press the button mishi.

But in order to speed up this world, he brought us the obligation of the new one, the great is never enough, and the most qualified one is the one who may be better informed in the future. On the other hand, analog light, which is replaced by digital light, is not subject to switching off. It is imperative that it be replaced, but the information base of this “world” is still being undermined by the light of new technologies. Evils and other types of assets that are not visible in the digital world, until then, were not visible in the analog world.

WWW hyperstructure

However, looking through Web pages is not at all easy after burning out, like at the bottom of a book. The most important power of the WWW is the hypertext organization of connections between Web pages. Moreover, these connections operate both between pages on one server and between different WWW servers.

Namely, the keywords that go into hyperlinks are displayed on the Web page by color or symbol. By clicking on this word, you will be directed to review the other document. Moreover, this document may be on another server, in another country, on another continent. Most users of the Internet have no idea where the server is located, with which one they are connected to. Figuratively speaking, in one session of work it is possible to “fly” around the earth’s core several times.

The great fear lies in the fact that he will be ready to turn back from this change. The digital world will bring us wonderful speeches and will be richer and more dynamic, as if this digital revolution was more democratic and better recommended. The analogue system is still around today, but the digital system is increasingly in fashion.

Guilty obligations are increasingly being distributed between the sovereign power and private power, in order to make digital access available to everyone, thereby conferring marriage. Nowadays, when we talk about developments or innovations, it is simply impossible not to connect this fact with technology, since everything is connected with it. Technology moves the light, which vibrates the development, but does not mean that it can be disturbed without caution, as can be seen below.

The role of the key for the link can be determined not only by the text, but also by a small picture, a photograph, or an indicator of a sound document. Once the term “hypertext” is replaced by the term “hypermedia”.

You can get to that same Web site using different routes. The analogy with the sides of a book does not work here. At the bottom of the book there is a song of sequence. There are no such sequences on web pages. The transition from one side to the other is accomplished through hyperlinks that create a boundary like a spider web. Enter the name of the system.

Technology has been the biggest breakthrough all the time, and through it a lot of others have come out, which allowed the predecessors to overcome the miraculous discoveries that generations have revealed, since the number of work places has increased b. Countries, which are also economic powers, have also made contributions to technological developments.

It is clear that the Internet is an important tool that is rapidly growing with fate, so today it is practically necessary to know how to deal with technological issues that may be present in the work scenario. The professional of this century is guilty of realizing that he may end up invading areas other than his own. Technological evolution has made the market very brutal. Advancement to professionalism in various galuzahs.

As stated above, you can also say:

The World Wide Web is an information system with hyperlinks distributed throughout the world, which is based on the technical basis of the worldwide Internet network.

Browser is a WWW client program. The problem of searching for information on the Internet

Navigating through the web allows you to use a special software program called a Web browser after the English word “browse.” Using a browser, you can find the information you need in a variety of ways. The shortest route - for additional web-site addresses. You type this address on the keyboard, press the enter key and press the right button.

He has a garniy and filthy beak. They only remember the good, but the bad side is forgotten, perhaps through unknown information about those who have not very good inheritances. The technology was created during the outbreak of the war, as it would become vikorist in military camps. Today, the war is in the hands of evildoers, who are victorious against snakes for the blow, who were killed and pedophiles, who are victorious for this purpose for the depletion of children's world. The nature of mass information requires precautions during the current period for moisture safety.

The other way is a search. You can start from your home page with hyperlinks. In this case, there is a danger of not going there, getting lost in the cobwebs, getting lost in a remote corner. In this case, the browser allows you to go back in any number of steps and continue your search along a different route. Such a joke is similar to wandering in an unknown forest (though it’s less safe).

Nowadays, the evolution of technology brings security to students who suffer from doubts about which profession to pursue, because there is a list of professions of the future, and others, who are talking about, will not know. Robot workers are also a little afraid of realizing that one fine day they will replace people with machines, which will lead to mass unemployment in this world.

At this point, one realizes that the only way will be open in the future to gain new knowledge. It’s amazing how the Internet has reached a high global significance in recent years, which is comparable to the wealth of fantastic outputs that we are all too familiar with. We can say that the technological evolution of this great measure lies in the fact that it has called for such an expansion and growth, but not only those who use the Internet for what they have today. This success is explained by the central idea of ​​the Internet, as presented in its initial concept: it is not a new product, but a collection of various human needs, such as storage and increased knowledge. organized and, first of all, accessible and affordable.

It is not surprising that this measure has become a larger part of our life, even if it were not another form of everyday life. Any social reaction to the Internet inevitably calls to mind: how did freedom for people on the Internet take root? Here are just a few of the most common problems, such as disrupting the Internet and possibly losing access for the last three hours.

A good example of these problems of security and freedom is that governments and powers are trying to monitor and control the flow of any information on the Internet. The uprising of the population of Mitevo, they passed from the private population of the skin of the population, or the population, which is now common: in the history of mankind there is something that covered the entire human population, which is similar to superspreadness: the region and binding us all.

Structure and principles of the World Wide Web

The World Wide Web hosts millions of web servers that connect to the Internet and are distributed all over the world. A web server is a program that runs on a connected computer and uses the HTTP protocol to transfer data. In its simplest form, such a program takes an HTTP request to a new resource, finds the corresponding file on the local hard drive, and sends it to the computer. More complex web servers can dynamically distribute resources from HTTP requests. To identify resources (most often files or parts thereof), the World Wide Web uses new URI resource identifiers. Uniform Resource Identifier). To identify local resources, the vikorists use one-man URL resource locators (English). Uniform Resource Locator). Such URL locators use URI identification technology and the DNS domain name system. Domain Name System) - the domain name (or directly the IP address in the digital record) enters the URL store for assigning a computer (more precisely, one of its edge interfaces), which contains the code of the required web server.

To view the information received from the web server, a special program - a web browser - is installed on the client computer. The main function of a web browser is to display hypertext. The world wide web is inextricably linked with the concepts of hypertext and hyperpower. Most information on the Internet is hypertext itself. To make it easier to create, save and display hypertext on the World Wide Web, HTML language is traditionally used. HyperText Markup Language), language markings for hypertext. The work of marking up hypertext is called layout; the work of marking up hypertext is called a web master or web master (without a hyphen). After HTML markup, the resulting hypertext is placed in a file, such an HTML file being the largest resource on the World Wide Web. Once the HTML file becomes accessible to the web server, it is called a web page. A set of web pages creates a website. Hypertext is added to the hypertext of web pages. Hyper-power helps users of the World Wide Web easily move between resources (files), regardless of whether they are resources on the local computer or on a remote server. The hyperpower of the web server is based on URL technology. (2 shots)

For the sake of ambiguity, in addition to controlling the shocks that arise from the “truth,” one chooses how people think and behave. Regardless of the recent discovery and adoption of the economic model, China is losing one step from its recent past. However, like until marriage, the Internet imposes norms and control. The concept of anonymity discourages many people from accepting evil actions that may be burned with the same energy and intense work of the “real world”. We have spent so many hours on those things that are absolutely impossible to recreate the Internet as the main hero in our life.

History of the World Wide Web

The winemakers of the world's web are respected by Tim Berners-Lee and, to a lesser extent, Robert Cayo. Tim Berners-Lee is the author of HTTP, URI/URL and HTML technologies. In the 1980s, a family of wines worked for the European Council for Nuclear Investigations (French. Conseil Européen pour la Recherche Nucléaire, CERN) software consultant. There, near Geneva (Switzerland), I wrote the Enquirer program for my needs. « Enquire» , can be easily translated as “Dozvidnik”), which championed special associations to save data and laid the conceptual foundation for the World Wide Web.

There are a lot of legal assets associated with the virtual world, and its protection is necessary for adequate health for everyone. For this purpose, reasonable control is required along the way. To begin with, create security in the virtual world, in other words, to ensure freedom of expression and harmless information about the Russian Revolution - until now, it is not clear.

Hello, fellow readers of the blog site. We all live in the era of the global Internet and the terms site, web, www (World Wide Web - global web, global network) reach us often and especially not in the same way.

I also warn against other authors, and also against the most recent spivozmovniks. “Site”, “Internet”, “interface” and the abbreviation “WWW” have become such basic concepts for us that even thinking about them doesn’t matter. However, the first website was born less than twenty years ago. What is the Internet?

Even though it may last a long time, until the advent of the global watchdog (WWW), 99.9% of the planet's inhabitants were still unaware of its existence, because they were mostly fakists and enthusiasts. At the same time, the Eskimos know about the cosmos, in whose language this word is related to the origin of shamans who joke around in the balls of light. So let’s discover for ourselves what the Internet is, a website, the world wide web, and everything else.

What is the Internet and its importance in relation to the global WWW?

The most miraculous fact that can be stated is those that The Internet does not care for Vlasnik. In essence, this is the unification of several local areas (we will always accept global standards, and the TCP/IP protocol itself), which is supported in the workplace by edge providers.

And the thought is that due to the ever-increasing media traffic (video and other important content that moves in tons at a time), the Internet will inevitably collapse through its currently limited bandwidth. The main problem in this plan is the renewal of the border control system, which will become a global network, in the Swiss system, which will be streamed in advance by the necessary additional expenditures. But I think that the problem will be solved in a world of aging collapse, which will already appear around the segments of the border that operate at high rates.

Now, in light of the fact that the Internet is essentially nothing, it is clear that many powers, trying to introduce censorship globally, want to identify them (and the most popular WWW warehouse at the moment) z.

There really is no water in the soil under these fruit trees, because The Internet is all about communication or, in other words, the personal information can be checked from the phone or sent by a regular paper. Try to impose sanctions until the paper is widened by the planet. In addition to sanctions outside the state, in fact, it can only be limited to sites (information islands at the same time) that become accessible to investors through the world wide web.

The first changes of mind created by the global web and the Internet began to grow... How do you respect, in what role? It’s amazing, even back in 1957. Of course, the military needed such a net (and, of course, the USA, where would we be without them) to prevent the outbreak of military activities due to the stagnation of nuclear weapons. They created the limit to last for a long time (about 12 years), but it was entirely clear that the computers were still in their infancy.

But their efforts were entirely due to the fact that, until 1971, the power between the military departments and major universities of the United States was eliminated. Thus, the Email transfer protocol became the first way to use the internet for the needs of koristuvachs. A couple more about those who have already discovered the Internet overseas. Until the early 1980s, the basic protocols for transmitting data (postal) were standardized, as well as the protocol for so-called Usenet news conferences, which was similar to postal, but allowed for organization similar to forums.

And through a series of rocks, the idea of ​​​​creating a domain name system (DNS - plays the most important role in the established WWW) and the appearance of the world's first protocol for searching via the Internet in real time - IRC (at the Russian platform) - Irka). Vіn allowed to chat in the middle. Science fiction, which was accessible and accessible to even a small number of inhabitants of planet Earth. Ale tse tilki still.

During the 1980s and 1990s, there are many significant periods in the history of infrastructure development, which are significant, and have a significant impact on the future. With such a widening of the global horizon in the minds of the current inhabitants of the planet there is almost one single person. Tim Berners-Lee:

Berners-Lee is an Englishman who was born into a family of two mathematicians who devoted their lives to the creation of one of the first computers in the world. The world itself has already learned that the Internet, website, e-mail, etc. From the beginning of the world wide web WWW (World Wide Web) he created for the needs of nuclear research Cern (they have the same collider). The task lay in the manual placement of all scientific information available to the concern within its borders of power.

For the best results, you need to understand everything that is contagious with the main elements of the WWW (those that we respect on the Internet, the little things that don’t understand its essence). It is based on the principle of organizing information, which is called. What's this? This principle was invented a lot earlier and was used in such an organization of the text, if the linearity of the story was replaced by the possibility of transition from different messages (links).

The Internet is hypertext, hyperpower, Urli and zalizo

Of course, hypertext can be read in different sequences, thereby distinguishing different variants of linear text (well, as Internet users with experience, it may be obvious and obvious, but also la revolution). The role of hypertext nodes is small, which is simply called senders.

As a result, all the information currently available on computers can be represented as one great hypertext, which includes an incurable, anonymous node (hyperpower). Everything that was dissected by Tim Berners-Lee was transferred from the local CERN network to what we today call the Internet, after which the Web began to gain popularity at a crazy pace (the first fifty million users of the World Wide Web bullets are registered without delay the first five rocks of sleep).

To implement the principle of hypertext and hyperpower, it was necessary to create and develop a number of speeches from scratch. First of all, we need a new data transfer protocol, which we now know HTTP protocol(at the beginning of the address of all websites you will find a clue about the one or about the stolen version of HTTPs).

In other words, it was dismantled from scratch, an abbreviation that is now visible to all webmasters in the world. Also, we have removed the tools for transferring data and creating websites (a set of web pages and web documents). How can I apply for these documents?

The first allows you to identify a document on the local server (site), and the other allows you to add a domain name URI to the identifier (which clearly indicates the identity of the document to the website hosted on the server) or IP address (a unique digital identifier) ​​Index of all devices in the global or local local boundaries). ). Read in more detail for guidance.

There was only one more month left to earn in order for the world wide web WWW to find, request and become demanded by the kristuvachs. Do you know which one?

Well, of course, there was a need for a program that could display on the computer of the client instead of any web page (behind the additional URL address). Having become such a program. As we talk about today, there are not so many main traders on this market, and I decided to write about all of them after a short glance:

1. (IE, MSIE) - the old guard is still in service
2. (Mazila Firefox) – another veteran is not going to give up his position without a fight
3. (Google Chrome) - an ambitious newcomer who wanted to achieve leadership in the shortest possible time
4. - there is a lot of love in RuNet, but the browser is gradually losing popularity
5. - Zaslanets from the apple camp

Timothy John Berners-Lee independently wrote the world's first Internet survey program and called it, without further ado, the World Wide Web. Although there was no limit to the thoroughness, this browser itself became possible to monitor the entire WWW planet.

This, of course, reflects the fact that all the necessary tools for the daily Internet (based on the most popular warehouse) are created by just one person in such a short hour. Bravo.

A short time later, the first graphical browser, Mosaic, appeared, from which we started and many from daily observers (Masila and Explorer). The Mosaic itself became the only drop that could not be washed away, otherwise showing interest in the Internet(And to the whole world) among the primary inhabitants of planet Earth. The graphical browser is completely on the right, and the one below is textual. Everyone loves to admire pictures and even loves to read.

What is noticeable is that Berners-Lee did not take away even large sums of pennies, but, for example, as a result they took away either, wanting to produce wine for the global measure, singly, still more.

So, one year ago, an additional addition to Berners-Lee’s Html movie was added. Finally, some of the operators in Html are no longer needed, and they have been replaced by richly flexible tools of cascading style sheets, which allowed us to truly promote the versatility and flexibility of the design of sites that I can now create huddle. If you use the correct CSS rules, you need simpler, lower layouts. Prote beauty attracts victims.

How is the Internet controlled and the global border in the middle?

Ale, let's marvel what is Web (www) And how does it work to post information on the Internet? Here we are stuck with this very phenomenon called a website (web is a network, and site is a place). Well, what is the “place in the dark” (analogous to the place under the sun in real life) and how can we get rid of it?

What is internet? However, it consists of invisible and unavoidable meanings for the users of channel-distributing devices (routers, switches). The WWW network (what we call the Web or the world wide web) consists of millions of web servers, which are programs running on three modified computers, which are necessarily responsible for connection (in 24/7 mode ) to the global web and use the HTTP protocol for data exchange.

The web server (program) retrieves the request (most often from the user’s browser, which opens the message or enters the Url in the address bar) for the text of the document hosted on its own server. In its simplest form, a document is a physical file (with advanced HTML extensions, for example) that resides on the server’s hard drive.

In the larger folding version (with vikoristan), the document will be formed by software onto the sheet.

To view the downloaded page, the site needs a special software program on the client side called a browser, which draws a fragment of hypertext in a manual view on that information display device. ї, this installation browser (PC, phone, tablet, etc.) . ). The whole thing is simple, so as not to go into details.

Previously, this website was located physically on your computer. This was connected, most importantly, with the weak computational tension of the PCs that were evident at that time. However, in any case, the computer running the web server program and hosting the site on a new site will inevitably have a lot of connections to the Internet. Doing this at home is difficult and expensive, so in order to save websites, you should hire the services of hosting companies that specialize in this.

Service to hosting through the popularity of WWW it is possible to immediately deliver what is required. Due to the demands of daily PCs, which are growing over time, hosters have the opportunity to host many websites on one physical computer (virtual hosting), and hosting one site on one physical PC has become called service.

When using virtual hosting, all websites hosted on a computer (called a server) can be assigned one IP address, or they can be separated from each other. The essence does not change and can only be applied indirectly to the placements there on the Website (a bad entity on one IP may not appear on sound systems, but they all have to row with the same comb).

Now let's talk a little about domain names of websites and their meanings on the World Wide Web. Each resource on the Internet has its own domain name. Moreover, the situation may be complicated if one and the same site may have a number of domain names (as a result, mirrors or aliases appear), and so, for example, for many resources one and the same domain names may be abused.

Also, for such serious resources, there is a concept like a mirror. In this case, the site’s files may be shared on different physical computers, and the resources themselves may have different domain names. But there are all the nuances that can only confuse the ears.

The tumultuous development of the Internet network, which has been observed for the last 15 years, just before the emergence of the World Wide Web. “The World Wide Web” is a complete translation of the English phrase “World Wide Web”, which is often referred to as WWW or the Web.

Technology of the World Wide Web. The World Wide Web uses hypertext technology, in which documents are linked to each other for help hyperpower.

In yakosti pokazchikiv posilan On web pages, there may be fragments of text that are visible in color and under the chairs, as well as graphic images that are visible in the frame. Activation of the order form on the output Web page (for example, by clicking a mouse) results in a transition to the required Web page (Fig. 6.10).

Worldwide spider web- hundreds of millions of Web servers on the Internet, which includes hundreds of billions of Web pages that use hypertext technology.

The web page can be multimedia, so you can place a variety of multimedia objects: graphic images, animation, sound and video.

The web page can be interactive, in order to fill out forms with fields that are used when registering for free e-mail, when making purchases in online stores, etc.

Thematically related Web pages depend on the presentation of the form Website, so that there is a complete system of documents linked together for a single purpose for additional purposes.

Web site addresses. Currently, a large number of Web pages are stored on Internet Web servers. You can find a web site on the Internet using the following web site.

Web site addresses includes the method of access to the document and the name of the Internet server on which the document is located.

The HTTP (Hyper Text Transfer Protocol) is used as a method of accessing Web pages. When recording a protocol, your name is followed by a double box and two lines: http://

As an example, let's write down the address of the title page of the Web site "Informatics and information technologies." The page is hosted on the server iit.metodist.ru, so the addresses appear as follows:

http://iit.methodist.ru

Browser. Viewing Web pages is done with the help of special viewing programs - browsers. Currently, the most widely used browsers are Internet Explorer, Mozilla and Opera.

The browser window (Fig. 6.11) contains standard program window elements:
- window menu for entering command sets File, Editing, View, Vibrane, Serviceі Dovidka;
- a toolbar, buttons that allow you to switch from one Web page to another (buttons Forward, Back, Dodoma), as well as with the process of their fascination (buttons Zupiniti, Onoviti);
- text field Addresses:, to any Internet address of the required Web site, enter from the keyboard or select from the list;
- I am working in the area where Web stories are viewed.

Small 6.11. Browsers Internet Explorer, Mozilla and Opera

Virtual roads along the World Wide Web. If your computer is connected to the Internet, you can launch one of the browsers and go on a virtual journey across the World Wide Web. The browser will automatically be attracted to the original Web page (the address of the Web page at which the price starts can be changed by further setting up the browser).

When you open a web site in a browser on your computer, you will have to go through a long journey from a remote Internet server through information transmission channels through a number of intermediate servers on the Internet. The importance of the Web site depends on the size of the connection to the Web server, such as the number of intermediate servers and the number of communication lines that transmit information from the server to the server. A situation is possible when the Web site is used more than from a server located on another continent than from a server located on the same street.

To go to another Web page in the text field Addresses: you must enter your Internet address. There are many web pages that place hyper-power on other web sites, so further along the World Wide Web you can continue to activate one of them.

In the process of reading a book (handbook, guide, encyclopedia) you often need to turn back to the material you read. To find the necessary pages, you often insert so-called “bookmarks” into the book. In the process of visiting the World Wide Web, you must save the Internet addresses of certain Web sites in your browser as “bookmarks.” To open such a page, it is enough to activate one of the “bookmarks”.

1. What is the function of hyperpower in the technology of the World Wide Web?

2. What are the parts of a web site address?

6.5. A short introduction. Write down the address of the Web site that is saved on the Internet server, registered in the first-level domain ru, the domain of another level schools, and may also have authority over the name www.

Electronic mail

Electronic mail (e-mail) is the most extensive service on the Internet. Vaughn is the historically first information service of computer measurements and highlights the obligatory evidence of high viscous and acidic lines.

Electronic mail poses a number of serious challenges compared to regular mail. The most important thing is the liquidity of the message. If a letter by regular mail can reach the addressee within days and days, then a letter sent by electronic mail will shorten the transmission hour to several tens of seconds or, at worst, to several years.

Another advantage is that the electronic sheet can be stored as a text message, as well as file attachments (programs, graphics, sound, etc.). In addition, electronic mail allows you to send notifications to multiple subscribers, forward lists to other addresses and others.

Email addresses. In order for the electronic sheet to reach the addressee, you, in addition to the notification itself, are obligated to enter the email address of the recipient of the sheet.

The first part of the mail address, usename, is of a rather special nature and is set by the customer himself during the registration of the mail screen. Another part of server.ru is the name of the mail server on the Internet, on which the client has registered his mail screen.

Email addresses is written as a song form and consists of two parts, separated by the @ symbol: [email protected]

E-mail addresses are written in Latin characters only and are not required to include spaces. For example, since the mail server is named metodist.ru, the names of the mail screens of the correspondents will look like:

[email protected]

The addresses of e-mail subscribers are saved on the customer’s computer in the “Address Book” database. The address book contains the subscriber's name, email address, telephone number and other data (Fig. 6.12).

Small 6.12. Database "Address Book"

Functioning of electronic mail. Internet users can register a mail screen on the provider's mail server, which will store electronic sheets that are transmitted and stored.

For additional mail programs, notifications are created on the local computer. At this stage, in addition to writing the text of the notification, it is necessary to indicate the address of the recipient of the notification (can be taken from the “Address Book”), the topic of the notification and, if necessary, insert files into the notification.

The process of sending a notification begins by connecting to the Internet and delivering the notification to your mail screen on a remote mail server. The mail server is immediately informed through the system of mail servers on the Internet to the mail server holding up to your mail screen.

To pick up a sheet, the recipient must connect to the Internet and deliver the mail from his mail screen on a remote mail server to his local computer (Fig. 6.13).

Mail programs are required to provide you with the same number of additional services for working with mail (selecting an address from the address book, automatically sending notifications for the specified addresses, etc.).

Postal program Outlook Express. To work with electronic mail, special mail programs are required. The email program Outlook Express is becoming very popular, as it is connected to the Windows operating system. After launching Outlook Express, a program window appears that consists of four parts (Fig. 6.14).

Small 6.14. Outlook Express mailbox window

At the top left part of the window there is a list of folders in which electronic sheets are saved:
- Exit- Remove leaves;
- Weekend- place the lists to be sent from the moment of creation until the moment of delivery from the client’s local computer to the provider’s mail server;
- Nadislani- place all messages delivered to the mail server;

File archives

File archive servers Tens of thousands of Internet servers are file archive servers, and hundreds of millions of files of various types are stored on them (programs, device drivers, graphics and sound files, etc.). The availability of such file archive servers is even handy for computer users, as a large number of necessary files can be “obtained” directly from the Internet.

File servers are supported by many software companies and manufacturers of computer hardware components and peripheral devices. The software that is hosted on such servers is completely universal and intellectually cost-free, and by “downloading” another file, the user does not violate the law on copyright on the software.

File storage managers. For the convenience of users, many file archive servers (freeware.ru, www.freesoft.ru, www.download.ru) have a Web interface that allows you to use them with different browsers. Browsers are integrated systems for working with various information resources on the Internet and also include file access managers.

Prote, more useful for working with file archives, there are specialized file management managers that allow the file to continue to be stored after the connection with the server is disconnected. File acquisition managers provide detailed reporting information in numerical and graphical form about the file acquisition process (obligation to the file, obligation to the acquired part, including in hundreds, the speed of acquisition, the hour of acquisition, the past, and In.).

Some file management managers can achieve greater efficiency by dividing a file into parts and simultaneously capturing all parts. For example, in the FlashGet file acquisition manager, the process of acquiring the skin of a file is presented in a graphical form in the lower part of the program window (Fig. 6.16).

Addresses to the file on the file archive server. Access to files on file archive servers is possible using either the HTTP protocol or the special FTP (File Transfer Protocol) file transfer protocol. The FTP protocol allows you to transfer files from remote file archive servers to a local computer, and, finally, to transfer files from a local computer to a remote server.

File addresses includes a method for accessing the file and the name of the Internet server on which the file is located.

Since the FTP file transfer protocol is used to access the file file.exe, which is stored on the ftp.metodist.ru server, the file addresses will be written as follows:

ftp://ftp.metodist.ru/file.exe

Spilling on the Internet

Nowadays, online searches on the Internet are increasingly expanding. The increased speed of data transmission and increased productivity of computers give users the ability to not only exchange real-time text messages, but also make audio and video calls. ok

Servers are built in real time. There are thousands of servers on the Internet that carry out real-time merging. Any player can connect to such a server and start a match with one of the servers or take part in a collective team.

The simplest method of sputtering "Rozmova", or chat(English chat) - the exchange of messages that are typed from the keyboard. You enter notifications from the keyboard and it appears in the window that all participants of the conference will be able to download at the same time.

If your computer, as well as the computers of your computers, has a sound card, microphone and headphones or speakers, you can exchange audio messages. However, “alive” Rozmova can only be found between two spivrozmovniks.

In order for you to be able to view each other and exchange videos, your computers must be connected to a Web camera.

Interactive connection with the additional ICQ system. In the future, interactive communication through ICQ servers has become increasingly popular (this triliteral abbreviation is created after the words “I seek you” - “I’m joking for you”).

The ICQ interactive messaging system integrates various forms of messaging: email, text messaging (chat), Internet telephony, file transfer, searching among people, etc. (Fig. 6.17).

Small 6.17. ICQ interactive linking program

Currently, there are approximately 200 million registered users in the ICQ system, each customer has a unique identification number. After connecting to the Internet, the client can start downloading by registering with the ICQ system and connect to the Internet at the moment.

Internet telephony. Internet telephony is used to transmit voice data via the Internet. Internet telephony providers, with the help of special equipment, link between themselves the computer network of the Internet and the primary telephone network. A customer can quickly access Internet telephony services and dial directly from a computer (div. small 6.18) or from a dial telephone by first dialing the number of the Internet telephony provider.

Internet telephony can be used for calling calls in remote locations and at the ends of the world, since such a connection is very cheap for the tariffs of interstate and international telephone calls.

1. What forms of real-time communication exist on the Internet?

Mobile Internet

Merezha mobile phone. The trend of mobile phone communication has taken over almost the entire world, and the number of private mobile phones is approaching one billion people. The exchange of information between mobile phones takes place through an additional layer that consists of an antenna station connecting the information transmission channels.

The mobile phone connection allows you to transmit both voice notifications and data. With additional mobile phones, you can exchange short SMS text messages, as well as multimedia MMS messages, which allow you to enhance the ringtones for phones and graphic images (for example, photographs included in the phone camera).

Exchange of data between a mobile phone network and a computer network on the Internet. The mobile phone network and the Internet computer network allow the transmission of data and voice notifications, and their information resources are completely combined. Mobile phone operators and Internet providers ensure the ability to transfer data between these boundaries (Fig. 6.18).

The exchange of data allows, for example, from a mobile phone to send email notifications to a mail screen on the Internet, and from a computer connected to the Internet to send SMS notifications to a mobile phone.

Access to the Internet with an additional mobile phone. Many models of mobile phones have a modem, so for drone-free Internet access you just need to connect your mobile phone to your computer and call your provider. Once you connect your computer to the Internet, you can “increase the price” of the World Wide Web, trade via e-mail, “obsess” files and access any other Internet resources, just like when you first connected Nanny cable channels. The disadvantage of such a connection is the low speed of data transmission (no more than 9.6 Kbps) and high connection speed.

Full-time high-speed Internet access from a mobile phone can be achieved using GPRS technology, where the maximum possible data transmission speed is 170 Kbps (which is approximately 3 times faster than access via telephone lines, what to do with each other). It is important that this technology provides instant access to the Internet, without the need to dial an Internet provider, and allows you to instantly conduct business via a mobile phone and exchange data between your computer and the Internet.

Connecting a mobile phone to a computer can be done in a variety of ways: using an additional cable to the COM port, using an additional cable to the USB port, or wirelessly to the infrared port (Fig. 6.19).

To access information resources on the Internet directly from mobile phones, you can use the WAP browsers. WAP sites are specially adapted to the capabilities of a mobile phone (bicolor graphics, small screen and small memory) and news, weather forecasts, exchange rates, etc. From WAP sites you can send notifications by email or take part in WAP chat.

Sound and video on the Internet

Sound and video files are a great source of information. To transfer such files over computer networks, standard digital formats require high-bandwidth lines. High fidelity digital stereo audio with a sampling rate of 48,000 times per second and 16-bit encoding depth delivers data transfer speeds equal to:

16 bits × 48,000 s -1 = 1,536,000 bits/s = 1,500 Kbit/s » 1.5 Mbit/s.

Digital video of the television standard requires image transmission at a data transmission speed of approximately 240 Mbit/s.

To change the volume of audio and video files without visible loss of capacity, special file compression methods are used, based on the fact that audio and video information is not intelligible to humans.

Stream audio and video. Technologies for transmitting streaming audio and video have become widespread on the Internet. These technologies transfer audio and video files in parts to a local computer buffer, which ensures the ability to stream them with a local modem connection. Reduced transmission speed of a channel can result in loss of sound or skipping of video frames for up to several hours.

To listen to streaming audio and watch streaming video, use multimedia programs (Windows Media Player, WinAmp, etc.). Before the streaming media file is created, the user can check the data transmission speed and adjust the creation speed.

It is possible to get a lot of radio from TV stations that provide information via the Internet. Web cameras are becoming widely popular, installed in various parts of the world (on the streets, in museums, in nature reserves, etc.) and continuously transmitting images (Fig. 6.20).

1.Why is it necessary to compress audio and video files for transmission via the Internet?

Globally, the Internet reaches consumers with its information resources and services (services), which are regularly used by nearly a billion people in all corners of the world.

The tumultuous development of the Internet network, which has been observed for the last 15 years, just before the emergence of the World Wide Web. “The World Wide Web” is a complete translation of the English phrase “World Wide Web”, which is often referred to as WWW or the Web.

Technology of the World Wide Web. The World Wide Web uses hypertext technology, in which documents are linked to each other for help hyperpower.

In yakosti pokazchikiv posilan On web pages, there may be fragments of text that are visible in color and under the chairs, as well as graphic images that are visible in the frame. Activation of the order form on the output Web page (for example, by clicking a mouse) results in a transition to the required Web page (Fig. 6.10).

Worldwide spider web- hundreds of millions of Web servers on the Internet, which includes hundreds of billions of Web pages that use hypertext technology.

The web page can be multimedia, so you can place a variety of multimedia objects: graphic images, animation, sound and video.

The web page can be interactive, in order to fill out forms with fields that are used when registering for free e-mail, when making purchases in online stores, etc.

Thematically related Web pages depend on the presentation of the form Website, so that there is a complete system of documents linked together for a single purpose for additional purposes.

Web site addresses. Currently, a large number of Web pages are stored on Internet Web servers. You can find a web site on the Internet using the following web site.

Web site addressesincludes the method of access to the document and the name of the Internet server on which the document is located.

The HTTP (Hyper Text Transfer Protocol) is used as a method of accessing Web pages. When recording a protocol, your name is followed by a double box and two lines: http://

As an example, let's write down the address of the title page of the Web site "Informatics and information technologies." The page is hosted on the server iit.metodist.ru, so the addresses appear as follows:

http://iit.methodist.ru

WWW-information web: Internet name system, domain names and IP addresses.

Worldwide spider web(English) World Wide Web) - a distributed system that provides access to interconnected documents located on different computers connected to the Internet. For the purpose of the All-World Pavutina, you also use the word web(English) web"pavutina") and abbreviation WWW.

The World Wide Web is run by hundreds of millions of web servers. Most of the resources on the World Wide Web are based on hypertext technology. Hypertext documents hosted on the World Wide Web are called web pages. A number of web pages, united by a common theme, design, and also interconnected by messages and therefore located on the same web server, are called a website. To view and view web pages, special programs are used - browsers. browser).

The World Wide Web sparked a revolution in information technology and a surge in the development of the Internet. Everyday people who talk about the Internet often pay attention to the cosmos itself. However, it is important to understand that it is not the same.

The World Wide Web hosts millions of web servers that connect to the Internet and are distributed all over the world. A web server is a computer program that runs on a connected computer and uses the HTTP protocol to transfer data. In its simplest form, such a program takes an HTTP request to a new resource, finds the corresponding file on the local hard drive, and sends it to the computer. More complex web servers based on HTTP requests dynamically generate documents using additional templates and scripts.

To view information received from the web server, a special program - a web browser - is installed on the client computer. The main function of a web browser is to display hypertext. The world wide web is inextricably linked with the concepts of hypertext and hyperpower. Most information on the Internet is hypertext itself.

To create, save and display hypertext on the World Wide Web, HTML language is traditionally used. HyperText Markup Language"Mova markings for hypertext"). The work of creating (laying out) hypertext documents is called layout, you can work as a webmaster or call it a layout designer - a layout designer. After HTML markup, the resulting document is saved as a file, and such HTML files are the main type of resources on the World Wide Web. Once the HTML file becomes accessible to the web server, it is called a web page. A set of web pages creates a website.

Hypertext of web pages is hyper-powerful. Hyper-power helps users of the World Wide Web easily move between resources (files), regardless of whether they are resources on the local computer or on a remote server. To identify local resources, the World Wide Web uses new URL resource locators (English). Uniform Resource Locator). For example, the entire URL of the main page of the Russian section of Wikipedia looks like this: http://ua.wikipedia.org/wiki/Head_story. Such URL locators use URI identification technology. Uniform Resource Identifier“Uniform resource identifier”) and the DNS domain name system (English) Domain Name System). The domain name (in this version ru.wikipedia.org) in the URL store means a computer (more precisely, one of its edge interfaces), which contains the code of the required web server. The URL of the streaming site can be added in the address bar of the browser, if most modern browsers want to more easily display the domain name of the streaming site.

The Worldwide Web (abbreviated) World Wide Web or WWW) - a set of information resources that are interconnected by telecommunications and based on hypertext data distributed throughout the world.

The fate of the people of the World Wide Web respects the year 1989. Of course, Tim Berners-Lee launched a comprehensive hypertext project, which has long since abandoned the name of the World Wide Web.

The creator of "pavutini" Tim Bernes-Lee, working in the laboratory of the physics of elementary particles of the European Center for Nuclear Research "CERN" in Geneva (Switzerland), together with his partner Robert Cayo, dealt with the problems of putting ideas into hypertext to generate information valuable middle ground, which would simplify the exchange of information between physicists .

Together, this work has become a document in which the concepts seem to be fundamentally important for the “web” in her immediate view, and was represented by the URI identifiers, the HTTP protocol and the HTML language. Without these technologies, it is no longer possible to discover the current Internet.

Berners-Lee created the world's first web server and the world's first hypertext web browser. On the first website, we described how to install a web server, how to install a browser, and how to install a browser. This site was the first Internet catalog in the world.

Beginning in 1994, the World Wide Web Consortium took over the development of the World Wide Web ( World Wide Web Consortium, WZS), which is organized and completed by Kim Bernes-Lee. The consortium develops and promotes technological standards for the Internet and the World Wide Web. WZS mission: “To fully unlock the potential of the World Wide Web by creating protocols and principles that guarantee the long-term development of Merezha.” WZS is expanding its “Recommendations” in order to gain insight into software products and equipment from other companies, in order to create a more thorough, universal and manual approach to the World Measurement.

Sound systems: storage, functions, principles of operation.

Poshukova system - this software and hardware complex is used for searching on the Internet and responds to the user’s request, which is specified in the form of a text phrase (search request), with a list sent to the information site, in order of relevance (obviously before asking). The largest international sound systems: "Google", "Yahoo", "MSN". The Russian Internet has - "Yandex", "Rambler", "Aport".

Describeable main characteristics of sound systems :

Povnota

Repetition is one of the main characteristics of the sound system, which means that the number of documents found in a search is up to the total number of documents on the Internet that satisfy the given search. For example, if there are 100 pages on the Internet that use the phrase “how to choose a car,” and only 60 of them were found in a search query, then the search frequency will be 0.6. Obviously, the higher the search, the less certainty that the buyer will not find the required document, because they have found it on the Internet.

Accuracy

Accuracy is another main characteristic of a sounding machine, as determined by the type of documents found by the operator. For example, since the command “how to choose a car” contains 100 documents, 50 of them contain the phrase “how to choose a car”, and in others there are simply words (“how to correctly select a radio and install it in a car”), then the accuracy is a guess respects with jealousy 50/100 (=0.5). The more precise the search, the sooner the correspondent will find the documents he needs, the less the confusion between them will be, the sooner the documents found will not answer the question.

Relevance

Relevance - no less important is the warehouse search, which is characterized by the hour that passes from the moment of publication of documents on the Internet until they are entered into the index database of the search system. For example, the next day, after the appearance of this new product, a large number of consumers turned to sound systems with unique inputs. Objectively, since the publication of new information on this topic, less progress has passed, the main documents have already been indexed and are available for search in the great search systems of the so-called “Swedish Base”, as it is updated several times a day.

Shvidkіst by search

The fluidity of the sound is closely related to its durability to the point of vantage. For example, according to Rambler Internet Holding LLC, as of today, the workday time to reach the Rambler search machine is approximately 60 requests per second. Such attraction will require a short time to process the right decision. Here the interests of the machine and the sound system are avoided: it is necessary to reject the results as soon as possible, and the sound machine is obliged to process queries as quickly as possible, so as not to miscalculate the calculation of upcoming requests.

Initiality

The accuracy of the results is an important component of a manual search. Over the course of more than one search, a search machine can find hundreds, or even thousands, of documents. Due to the unclearness of the words and the inaccuracy of the search, the first pages must be kept in place only the necessary information. This means that koristuvache often have to carry out their imperious search in the middle of the found list. Various elements of the page such as the sound system help you navigate the search results. http://help.yandex.ru/search/?id=481937.

A short history of the development of sound systems

At the beginning of the development of the Internet, the number of its customers was small, and the amount of available information was still small. Specialists in the scientific and research sphere have limited access to the Internet. At this time, searching for information on the Internet was not as relevant as it was now.

One of the first ways to organize access to information resources in the network was the creation of closed directories of sites, sending them to resources that were grouped together with the same topic. The first such project was the site Yahoo.com, which was launched in the spring of 1994. Since the number of sites in the Yahoo catalog has increased significantly, it has become possible to find the information you need from the catalog. The most common sense did not yet have a search system, because the search area was surrounded only by resources, such as in catalosis, and not by the entire Internet resources.

Catalogs were widely used in the past, but have practically lost their popularity. So, how to publish daily, important catalogs, only provide information about a tiny part of the Internet. The largest directory of the DMOZ network (also called the Open Directory Project) contains information about 5 million resources, just as the Google search engine database consists of over 8 billion documents.

The first full-fledged search system was the WebCrawler project, which was launched in 1994.

In 1995, Lycos and AltaVista sound systems appeared. For many years she remained a leader in the field of searching for information on the Internet.

In 1997, Sergei Brin and Larry Page created the Google search engine as part of a pre-study project at Stanford University. Google is the most popular search engine in the world!

In the spring of 1997, the Yandex search system was officially announced, which is the most popular on the Russian Internet.

Currently, there are three main international search systems - Google, Yahoo and MSN, which contain the power base and search algorithms. Most other sound systems (of which there are a great number) show similar results from three treatments. For example, AOL (search.aol.com) searches the Google wiki database, and AltaVista, Lycos and AllTheWeb search the Yahoo database.

Warehouse and principles of the robotic sound system

In Russia, the main search engine is Yandex, followed by Rambler.ru, Google.ru, Aport.ru, Mail.ru. Moreover, at the same time Mail.ru is a vikory mechanism and the Yandex search database.

Almost all great sound systems have a different structure than others. However, you can see the basic components for all sound machines. The significance of the structure may be less important in the appearance of the implementation of the mechanisms of interaction between these components.

Indexing module

The indexing module consists of three additional programs (robots):

Spider – a program designed to attract web pages. "Pavuk" ensures that the page is downloaded and collects all internal messages from that page. The HTML code of the skin page is required. To attract sites, robots use HTTP protocols. Pratsyuє “pavuk” in this way. The robot sends the request “get/path/document” and other commands to the HTTP request to the server. As a result, the robot receives a text stream to contain the service information and the document itself.

Page URL

date, if the side was invaded

http-header of the server connection

side body (html code)

Crawler ("mandrivny" spider) - a program that automatically goes through all the messages found on the website. Sees all messages on the page. Your task is to find out where the spider can go next, heading towards the destination or coming out from behind the address given in the list. Crawler, following the received messages, searches for new documents that are still unknown to the search system.

Indexer (robot indexer) - a program that analyzes web sites attracted by spiders. The indexer searches the warehouse and analyzes their current lexical and morphological algorithms. Analyze various elements of the page, such as text, headings, structural and style features, special service HTML tags, etc.

Thus, the indexing module allows you to search for messages on a given number of resources, search for pages that are shrinking, pull messages to new pages from the contents of documents and conduct a new analysis of these documents.

Database

The database, or the index of the search system, is a data saving system, an information array in which the parameters of all stored and processed by the document indexing module are saved through a special procedure.

Sound server

The sound server is the most important element of the entire system, since the algorithms that underlie its functioning are responsible for the power and strength of the sound.

The sound server works as usual:

Ottrimaniya from koristuvacha is subject to morphological analysis. Information is generated on the exact details of the skin document, which is located in the database (as it will be conveniently displayed in the snippet view, so that the text information can be entered on the search results page).

The extracted data is passed as input parameters to a special ranking module. Data processing for all documents is carried out, as a result of which a power rating is obtained for each document, which characterizes the relevance of the query entered by the customer and various warehouse documents that are stored in the index of the search system.

It is important to select a correspondent, this rating may be corrected by additional brains (for example, the title of “expansion of searches”).

Next, a snippet is generated, then for each found document from the table of documents, a title, a short abstract, the most consistent with the query and a message are sent to the document itself, and the found words are highlighted.

The selected search results are transmitted to the user as SERP (Search Engine Result Page) – pages where search results are shown.

As you can see, all these components are closely connected one to another and work together to create a smooth, folding mechanism for the sound system, which requires a large investment of resources.

The same search system does not consume all the resources of the Internet.

The skin-sensing system collects information about Internet resources using its unique methods, and forms a global database that is periodically updated. Access to this database is granted to koristuvacheva.

Search systems implement two ways to search for a resource:

Search for a thematic one catalogs - information appears to have a hierarchical structure. On the upper level - underground categories ("Internet", "Business", "Mystery", "Lighting", etc.), on the current level categories are divided into sections, etc. The lowest level is sent to specific web sites and other information resources.

Search for keywords (index search or detailed search) - koristuvach powers the search system washed down, What is made up of key words. System turns koristuvachevy overflow of the resources found for washing.

Most sound systems offer insults in two ways.

Sound systems can be local, global, regional or specialized.

On the Russian part of the Internet (Runet), the most popular search engines are Rambler (www.rambler.ru), Yandex (www.yandex.ru), Aport (www.aport.ru), Google (www.google.ru).

Most sound systemsimplemented in the form of portals.

Portal (English version)portal- main entrance, gate) is a website that integrates various Internet services: search services, mail, news, dictionaries, etc.

Portals can be specialized (such aswww. museum. ru) and zagalnymi (for example,www. km. ru).

Search for keywords

The set of keywords behind which the search is conducted is also called the search criterion or the search topic.

A query can be composed of one word or a combination of words combined with operators - symbols that the system indicates what action needs to be performed. For example: ask Moscow Peter to enter the operator I (this is how the space is taken), which indicates that you need to search for documents that contain offensive words - both Moscow and Peter.

In order for the search to be relevant (in English relevant - pre-verbal, which is worth checking), follow a number of hidden rules:

Regardless of the form in which the word is written in the capital, all word forms follow the Russian rules. For example, after the search for “kvitok” you will find the words “kvitkom”, “kvitku”, etc.

Great writers should avoid vikorism only in powerful names, so as not to overlook the message sent. If you ask the “Kovalovs,” for example, you will find documents about both the Kovalivs and the Kuznetsovs.

Bazhano sounded the sound of the sound, the vikorist and the number of key words.

If the required address is not among the first twenty known addresses, then change the entry.

The skin search system vikoristovuyu its language of queries. To get to know him, use the updated sound system

Great sites can implement information search systems between web pages.

If you ask in such systems for a joke, as a rule, you will follow the same rules that are used in global search systems, so we won’t ask for any information about it.

Search for extensions

Sound systems can be powered by a blower mechanism, which allows for the formation of a folding device. Going beyond the order Search for extensions Allows you to edit search parameters, specify additional parameters, and select the most customized form for displaying search results. Below we describe the parameters that can be specified during advanced search in the Jax1ex and Rambler systems.

Some search systems (for example, Yandex) allow you to enter natural language. Write what you need to know (for example: getting tickets for the train from Moscow to St. Petersburg). The system analyzes the request and displays the result. If it doesn’t influence you, go to the language of the questions.
