The relationship between the Internet and the World Wide Web. World Wide Web - World Wide Web. Internet like the World Wide Web
The World Wide Web(www)
As the Internet developed, more and more information was involved in its circulation, and navigating the Internet became increasingly difficult. Then the task arose to create a simple and understandable way to organize information posted on Internet sites. The new www (world wide web) service has fully coped with this task.
World Wide Web is a system of documents with text and graphic information posted on Internet sites and interconnected by hyperlinks. Perhaps this particular service is the most popular and for many users it is synonymous with the word INTErNET itself. Often, novice users confuse two concepts - the Internet and WWW (or Web). It should be recalled that WWW is just one of the many services provided to Internet users.
The main idea that was used in the development of the www system was is the idea of accessing information using hypertext links. Its essence is to include in the text of a document links to other documents, which can be located either on the same or on remote information servers.
www history begins from the moment when, in 1989, an employee of the famous scientific organization CErN Berners-Lee proposed to his management to create a database in the form of an information network that would consist of documents that included both the information itself and links to other documents. Such documents are nothing more than hypertext.
Another feature that sets www apart from other types of services is that through this system you can access almost all other types of Internet services, such as FTP, Gopher, Telnet.
WWW is a multimedia system. This means that using www you can, for example, watch a video about historical monuments or find out information about the World Cup. It is possible to access library information and recent photographs of the globe taken five minutes ago by meteorological satellites, along with.
The idea of organizing information in the form of hypertext is not new. Hypertext lived long before the advent of computers. The simplest example non-computer hypertext – these are encyclopedias. Some words in articles are marked in italics. This means that you can refer to the related article and get more detailed information. But if in non-computer hypertext you need to turn pages, then on the monitor screen, following a hypertext link is instantaneous. You just need to click on the link word.
The main merit of the above-mentioned Tim Berners-Lee is that he not only put forward the idea of creating an information system based on hypertext, but also proposed a number of methods that formed the basis of the future www service.
In 1991, the ideas that originated in CErN began to be actively developed by the Center for Supercomputing Applications (NCSA). It is NCSA that creates the hypertext language html documents, as well as the Mosaic program designed to view them. Mosaic, developed by Mark Andersen, became the first browser and opened new class software products.
In 1994, the number of www servers began to grow rapidly and the new Internet service not only gained worldwide recognition, but also attracted a huge number of new users to the Internet.
Now let's give the basic definitions.
www– this is a set of web pages located on Internet sites and interconnected by hyperlinks (or simply links).
web page is a structural unit of www, which includes the actual information (text and graphic) and links to other pages.
website– these are web pages physically located on one Internet node.
The www hyperlink system is based on the fact that some selected sections of one document (which can be parts of text or illustrations) act as links to other documents that are logically related to them.
In this case, those documents to which links are made can be located both locally and on remote computer. In addition, traditional hypertext links are also possible - these are links within the same document.
Linked documents may, in turn, contain cross-references to each other and to other information resources. Thus, it is possible to collect documents on similar topics into a single information space. (For example, documents containing medical information.)
Architecture www
The architecture of www, like the architecture of many other types of Internet services, is built on the principle client-server.
The main task of the server program is the organization of access to information stored on the computer on which this program is running. After startup, the server program works in the mode of waiting for requests from client programs. Typically, web browsers are used as client programs, which are used by ordinary www users. When such a program needs to obtain some information from the server (usually these are documents stored there), it sends a corresponding request to the server. With sufficient access rights, a connection is established between the programs, and the server program sends a response to the request to the client program. After which the connection established between them is broken.
To transfer information between programs, the HTTP protocol (Hypertext Transfer Protocol) is used.
www server functions
www-server is a program that runs on the host computer and processes requests coming from www clients. When receiving a request from a www client, this program establishes a connection based on transport protocol TCP/IP and exchanges information via HTTP. In addition, the server determines access rights to the documents that are located on it.
To access information that cannot be processed by the server directly, it is used lock system. Using a special CGI interface (Common Gateway Interface, General interface gateways) for exchanging information with gateways, the www-server has the ability to receive information from sources that would be inaccessible to other types of Internet services. At the same time, for end user, the operation of gateways is “transparent”, i.e., when viewing web resources in his favorite browser, an inexperienced user will not even notice that some information was presented to him using the gateway system
www client functions
There are two main types of www clients: web browsers and utility applications.
web browsers used for direct work from www and obtaining information from there.
Service web applications can communicate with the server either to obtain some statistics or to index the information contained there. (This is how information gets into search engine databases.) In addition, there are also service web clients, whose work is related to the technical side of storing information on a given server.
What is the World Wide Web?
The web, or “web,” is a collection of interconnected pages with specific information. Each such page can contain text, images, video, audio and other various objects. But besides this, there are so-called hyperlinks on web pages. Each such link points to another page, which is located on some other computer on the Internet.
Various information resources, which are interconnected by means of telecommunications and based on hypertext representation of data, form the World Wide Web ( World Wide Web, or WWW for short).
Hyperlinks link pages that are located on various computers located in different parts of the world. A huge number of computers that are united into one network is the Internet, and the “World Wide Web” is a huge number of web pages hosted on network computers.
Each web page on the Internet has an address - URL (Uniform Resource Locator - unique address, name). It is at this address that you can find any page.
How was the World Wide Web created?
On March 12, 1989, Tim Berners-Lee presented the project to CERN management unified system organization, storage and public access to information that was supposed to solve the problem of sharing knowledge and experience between the Center’s employees. Berners-Lee proposed solving the problem of accessing information on different computers of employees using browser programs that provide access to the server computer where hypertext information is stored. After the successful implementation of the project, Berners-Lee was able to convince the rest of the world to use common Internet communication standards using the Hypertext Transfer Protocol (HTTP) standards and universal language markup (HTML).
It should be noted that Tim Berners-Lee was not the first creator of the Internet. The first system of protocols that ensure data transfer between networked computers was developed by employees of the US Defense Advanced Research Projects Agency (DARPA) Vinton Cerf And Robert Kahn in the late 60s - early 70s of the last century. Berners-Lee only proposed using the capabilities of computer networks to create new system organizing information and accessing it.
What was the prototype of the World Wide Web?
Back in the 60s of the 20th century, the US Department of Defense set the task of developing a reliable information transmission system in case of war. Advanced agency research projects The USA (ARPA) proposed to develop a computer network for this. They called it ARPANET (Advanced Research Projects Agency Network). The project brought together four scientific institutions - the University of Los Angeles, the Stanford Research Institute and the Universities of Santa Barbara and Utah. All work was financed by the US Department of Defense.
The first data transmission over a computer network took place in 1969. A Los Angeles University professor and his students tried to log into Stanford's computer and pass the word "login." Only the first two letters L and O were successfully transmitted. When they typed the letter G, the communication system failed, but the Internet revolution took place.
By 1971, a network with 23 users was created in the United States. The first program was developed to send Email over the network. And in 1973, University College London and the Civil Services in Norway joined the network, and the network became international. In 1977, the number of Internet users reached 100, in 1984 - 1000, in 1986 there were already more than 5000, in 1989 - more than 100,000. In 1991, a project was implemented at CERN World-Wide Web(WWW). In 1997, there were already 19.5 million Internet users.
Some sources indicate the date of the emergence of the World Wide Web a day later - March 13, 1989.
Scientific and technological progress does not stand still, but is in constant development, search, and improvement. Perhaps the most useful invention of human genius, the Internet, was invented relatively recently, by the standards of the development of civilization. At its core, it is a unique data exchange tool.
Internet (Network, Internet) - virtual environment guaranteeing access to information resources, the elements of which are personal computers. They are combined into a single circuit and endowed with unique addressing features, using high-speed communication lines with host computers.
Internet is huge network, connecting countless devices. It serves to exchange information that exists on this network in various forms. Nowadays, not only computers can connect to the Internet. Cell phones, tablets, game consoles, other gadgets and even TVs can easily go online at any time.
The significance of this information space is undeniable due to the amazing communication capabilities between users of all devices connected to the Network.
IN technically, the online space is formed by countless computer devices connected to each other. Billions of PC users living in different countries communicate with each other every day, transmit and receive useful information, download arrays of digital data in the form of applications, programs, utilities; watch videos, listen to music.
The online environment has another important property – limitless possibilities information storage. Transmitted via the Internet personal experience In addition, it is a unique platform for informing the masses for modern media and a colossal repository of world knowledge.
What is the Internet?
In order for PC owners living on different continents to be able to freely use the services of searching for network resources, trunk cables are laid at the bottom of the ocean through which useful information is pumped around the clock.
A personal computer is controlled by special protocols. This is a kind of instruction that allows you to set rules for communication between devices. The single criterion for constructing a software protocol is the IP address. Thanks to this structure, each participant receives his own digital address, with the help of which search and identification takes place.
For example, after entering the name “novichkam.info” into the browser line, in a matter of moments the client finds himself on a web platform offering help to beginners. In technical terms, the software robot simply finds the IP address code that is assigned to a specific site.
The machine algorithm includes the following operations:
- the request is recorded by the main server, where the name of the desired thematic data array is stored;
- the name is found in memory of this resource, i.e. detecting the required IP address;
- the client lands on the website.
There are other protocols, such as HTTP. Requests in another way are carried out with the addition of a prefix http://
What is the World Wide Web (WWW)
For most representatives target audience Of great interest is the definition of an Internet service as the World Wide Web in abbreviation (WWW or simply WEB). Its definition is understood as a set of interconnected web pages, access to which is provided by a limited number of PCs connected to the Internet.
A set of text files marked up in HTML with link transitions, hosted on electronic platform, received the name of the website. You can get acquainted with the content of a particular website by activating the browser to search for the address name.
The web today is positioned as the most sought-after and popular service in the online space, i.e. Internet. An important element of the WEB are hypertext links. By clicking on the link the required document or by requesting a unique URL (name code, path) in the browser, a person can view desired array text.
Addressing system
If you enter an incorrect address name into the search bar or follow a broken link, the browser will promptly signal an error (confirm the absence of the required page). Often, upon request, a person gains access to an advertising (fraudulent) site.
In this situation, you should correct the inaccuracy in the query string field without attempting to examine the advertising website for security reasons. The fact is that these sites can be infected with a virus. If the resource was created for the purpose of fraud, then it would be useful to familiarize yourself with our section, where the most popular methods of deception on the Internet are perfectly described.
The main thing in the address of any website is the domain, which serves to make it easier to remember. The domain usually displays the address home page. However, it should be understood that for technical downloading of the page, computer device uses IP with protocol "12.123.45.5". Agree, this combination is much more difficult to remember than Domain name our website.
It is important to know that entering "http://" or the "WWW" prefix in search bar NOT required at all. It is better to use the services of a search engine, where the mistake made will be immediately corrected, and the domain can be entered without a zone that causes confusion.
What does the Internet give us?
- unlimited communication and communication
Many people are looking for like-minded people here, communicating on popular social projects and forums. Others like it unique service personal communication using ICQ or Skype. Visitors to a dating website expect to find their other half here;
- unlimited possibilities for entertainment and personal leisure

- much more. The information on our website will help you find out not only all the possibilities of this global network, but also great experience while being in it.
History of the creation and development of the Internet.
The Internet owes its origins to the US Department of Defense and its secret research conducted in 1969 to test methods that would allow computer networks survive during hostilities using dynamic message rerouting. The first such network was the ARPAnet, which combined three networks in California with a network in Utah under a set of rules called the Internet Protocol (IP for short).
In 1972, access was opened to universities and research organizations, as a result of which the network began to unite 50 universities and research organizations that had contracts with the US Department of Defense.
In 1973, the network grew to an international scale, combining networks located in England and Norway. A decade later, IP was expanded to include a set communication protocols, supporting both local and global networks. This is how TCP/IP was born. Shortly thereafter, the National Science Foundation (NSF) launched NSFnet with the goal of linking 5 supercomputing centers. Along with the introduction of the TCP/IP protocol, the new network soon replaced ARPAnet as the backbone of the Internet.
Well, how did the Internet become so popular and developed, and the impetus for this, as well as for turning it into an environment for doing business, was given by the emergence of the World Wide Web (World Wide Web, WWW, 3W, ve-ve-ve, three double) - systems hypertext, which made surfing the Internet fast and intuitive.
But the idea of linking documents through hypertext was first proposed and promoted by Ted Nelson in the 1960s, but the level of existing computer technology did not allow us to bring it to life, although who knows how it would have ended if this idea had found application?!
The foundations of what we understand today as the WWW were laid in the 1980s by Tim Berners-Lee while working on a hypertext system at the European Laboratory for Particle Physics (European Nuclear Research Centre). ).
As a result of these works, in 1990 the scientific community was presented with the first text browser (browser), which allows viewing text files linked by hyperlinks on-line. The browser was made available to the general public in 1991, but its adoption outside academia has been slow.
A new historical stage in the development of the Internet is due to the release of the first Unix version of the graphical browser Mosaic in 1993, developed in 1992 by Marc Andreessen, a student who interned at the National Center for Supercomputing Applications (NCSA), USA.
Since 1994, after the release of versions of the Mosaic browser for Windows and Macintosh operating systems, and soon after that - Netscape Navigator and Microsoft browsers Internet Explorer, begins the explosive spread of the popularity of the WWW, and as a consequence of the Internet, among the general public, first in the United States and then throughout the world.
In 1995, NSF transferred responsibility for the Internet to the private sector, and since that time the Internet has existed as we know it today.
Internet services.
Services (services) are types of services that are provided by servers Internet networks.
In the history of the Internet, there have been different types of services, some of which are no longer in use, others are gradually losing their popularity, while others are experiencing their heyday.
We list those services that have not lost their relevance in this moment:
-World Wide Web - the World Wide Web - a service for searching and viewing hypertext documents, including graphics, sound and video. -E-mail – electronic mail – transmission service emails.
-Usenet, News – teleconferences, news groups – a type of online newspaper or bulletin board.
-FTP – file transfer service.
-ICQ is a service for real-time communication using a keyboard.
-Telnet is a service for remote access to computers.
-Gopher – service for accessing information using hierarchical directories.
Among these services we can highlight services designed for communication, that is, for communication, transfer of information (E-mail, ICQ), as well as services whose purpose is to store information and provide access to this information for users.
Among the latest services, the leading place in terms of the volume of stored information is occupied by the WWW service, since this service is the most convenient for users and the most progressive in technical terms. In second place is the FTP service, since no matter what interfaces and conveniences are developed for the user, the information is still stored in files, access to which is provided by this service. Gopher and Telnet services can now be considered "moribund" because new information almost no longer reaches the servers of these services and the number of such servers and their audience is practically not increasing.
World Wide Web - World Wide Web
World Wide Web (WWW) - hypertext, or more precisely, hypermedia Information system searching for Internet resources and accessing them.
Hypertext - information structure, which allows you to establish semantic connections between text elements on a computer screen in such a way that you can easily transition from one element to another.
In practice, in hypertext, some words are highlighted by underlining or coloring them in a different color. Highlighting a word indicates that there is a connection between this word and some document in which the topic associated with the highlighted word is discussed in more detail.
Hypermedia is what happens if you replace the word “text” in the definition of hypertext with “any type of information”: sound, graphics, video.
Such hypermedia links are possible because, along with text information you can link any other binary information, for example, encoded sound or graphics. So, if a program displays a world map and if the user selects a continent on this map with the mouse, the program can immediately provide graphic, sound and text information about it.
The WWW system is built on a special data transfer protocol called the transfer protocol HTTP hypertext(pronounced "h-tee-pee", HyperText Transfer Protocol).
All content of the WWW system consists of WWW pages.
WWW pages are hypermedia documents of the World Wide Web system. They are created using the hypertext markup language HTML (Hypertext markup language). One WWW page is in fact usually made up of a set of hypermedia documents located on the same server, intertwined with mutual links and related in meaning (for example, containing information about one educational institution or about one museum). Each page document, in turn, can contain multiple screen pages of text and illustrations. Each WWW page has its own “title page” (English: “homepage”) - a hypermedia document containing links to the main components of the page. Addresses " title pages" are distributed on the Internet as page addresses.
A set of Web pages interconnected by links and designed to achieve a common goal is called a Web site.
Email.
Email appeared about 30 years ago. Today it is the most widespread means of exchanging information on the Internet. The ability to receive and send email can be useful not only for communicating with friends from other cities and countries, but also in a business career. For example, when applying for a job, you can quickly send out your resume using e-mail to various companies. In addition, on many sites where you need to register (on-line games, online stores, etc.) you often need to provide your e-mail. In a word, e-mail is a very useful and convenient thing.
Electronic mail (Electronic mail, English mail - mail, abbreviated e-mail) serves for transmission text messages within the Internet, as well as between other email networks. (Picture 1.)Using e-mail, you can send messages, receive them in your email inbox, respond to letters from correspondents, send copies of letters to several recipients at once, forward a received letter to another address, use logical names instead of addresses, create several subsections mailbox for various types of correspondence, include various sound and graphic files in letters, as well as binary files- programs.
For use E-mail computer must be connected to telephone network via modem.
A computer connected to a network is considered a potential sender and receiver of packets. Each Internet node, when sending a message to another node, splits it into fixed-length packets, usually 1500 bytes in size. Each packet is provided with a recipient address and a sender address. Packets prepared in this way are sent over communication channels to other nodes. When receiving any packet, the node analyzes the recipient's address and, if it matches its own address, the packet is accepted, otherwise it is sent further. Received packets related to the same message are accumulated. Once all packets of one message are received, they are concatenated and delivered to the recipient. Copies of packets are stored on sending nodes until a response is received from the recipient node indicating successful delivery of the message. This ensures reliability. To deliver a letter to the recipient, you only need to know his address and the coordinates of the nearest mailbox. On the way to the addressee, the letter passes several post offices(nodes).
Service Internet FTP(file transfer protocol) stands for protocol
file transfer, but when considering FTP as an Internet service there is
not just a protocol, but a service - access to files in file
archives.

TELNET service
The purpose of the TELNET protocol is to provide a fairly general, bidirectional, eight-bit byte-oriented means of communication. Its main purpose is to allow terminal devices and terminal processes to communicate with each other. It is intended that this protocol can be used for terminal-to-terminal communication ("bundling") or for process-to-process communication ("distributed computing").
Figure 3. Telnet terminal window
Although a Telnet session has a client side and a server side, the protocol is actually completely symmetrical. After establishing a transport connection (usually TCP), both ends of it play the role of “network virtual terminals” (English). Network Virtual Terminal, NVT) exchanging two types of data:
Application data (that is, data that goes from the user to the text application on the server side and back);
Telnet protocol commands, a special case of which are options that serve to understand the capabilities and preferences of the parties (Figure 3).
Although a Telnet session running over TCP is full duplex, the NVT should be considered a half-duplex device that operates in line buffered mode by default.
Application data passes through the protocol without changes, that is, at the output of the second virtual terminal we see exactly what was entered at the input of the first. From a protocol point of view, data is simply a sequence of bytes (octets), which by default belong to ASCII set, but with the option enabled Binary- any. Although extensions have been proposed to identify a character set, they are not used in practice.
All application data octet values except \377 (decimal: 255) are transmitted as is over the transport. The \377 octet is transmitted as a \377\377 sequence of two octets. This is because the \377 octet is used at the transport layer to encode options.
The protocol provides minimal functionality by default and a set of options that extend it. The principle of negotiated options requires negotiations to take place when each option is included. One party initiates the request, and the other party can either accept or reject the offer. If the request is accepted, the option takes effect immediately. Options are described separately from the protocol itself, and their support by software is optional. Protocol client ( network terminal) instructs to reject requests to enable unsupported and unknown options.
Historically, Telnet was used for remote access to the interface command line operating systems. Subsequently, it began to be used for other text interfaces, right up to MUD games. Theoretically, even both sides of the protocol can be not only people, but also programs.
Sometimes telnet clients are used to access other protocols based on the TCP transport, see Telnet and other protocols.
The telnet protocol is used in the FTP control connection, that is, logging into the server telnet command ftp.example.net ftp for debugging and experimentation is not only possible, but correct (unlike using telnet clients to access HTTP, IRC, and most other protocols).
The protocol does not provide for the use of either encryption or data authentication. Therefore, it is vulnerable to any type of attack to which its transport is vulnerable, i.e. TCP protocol. For the functionality of remote access to the system, it is currently used network protocol SSH (especially its version 2), when created, the emphasis was placed specifically on security issues. So keep in mind that a Telnet session is very insecure unless it is on a fully controlled network or with security in place. network level(various implementations of virtual private networks). Due to its unreliability, Telnet was long abandoned as a means of managing operating systems.

The Internet is occupying an increasingly important place in our lives. No other technology created by man has gained such widespread popularity. Internet - the World Wide Web, which covers the entire Earth, enveloping it in a network of television towers. It began to gain its popularity back in the relatively distant 1990s. In the article we will discuss where it came from and why it became so popular.
Internet like the World Wide Web
The second name of such a plan was not without reason. The fact is that the Internet unites many users around the world. Like a spider's web, it envelops the entire globe with its threads. And this is not an ordinary metaphor, it really is. The Internet consists of wires and wireless networks, the latter of which are invisible to us.
But this is a lyrical digression; in fact, the Internet is connected to the World Wide Web (www, or Word Wide Web). It covers all computers connected to the Internet. On remote servers, users store necessary information, and can also communicate on the Internet. This name is often understood as the World Wide Web or Global Network.
It is based on several particularly important protocols, like TCP/IP. Thanks to the Internet, the World Wide Web, or in other words the Word Wide Web (WWW), carries out its activities, that is, transmits and receives data.
Number of users
At the end of 2015, a study was conducted, based on which the following data were obtained. There are 3.3 billion Internet users worldwide. And this is almost 50% of the entire population of our planet.
Such high rates were achieved thanks to the distribution cellular networks 3G and high speed 4G. Providers played an important role, thanks to the massive introduction of Internet technologies, the costs of maintaining servers and manufacturing fiber-optic cables decreased. In most European countries, Internet speeds are faster than in African countries. This is explained by the technical lag of the latter and the low demand for the service.
Why is the Internet called the World Wide Web?
Paradoxical as it may seem, many users are sure that the above term and the Internet are one and the same. This deep misconception that hovers in the minds of many users is caused by the similarity of concepts. Now we'll figure out what's what.
The World Wide Web is often confused with the similar phrase “World Wide Web.” It represents a certain volume of information based on Internet technology.
History of the World Wide Web
By the end of the 90s, the dominance of NSFNet over ARPANET technology was finally established in the world. Oddly enough, their development was carried out by one scientific center. ARPNET was developed by order of the US War Department. Yes, yes, the first to use the Internet were the military. And NSFNet technology was developed independently of government agencies, almost out of pure enthusiasm.
It was the competition between the two developments that became the basis for their further development and mass introduction into the world. The World Wide Web became available to the general public in 1991. It had to work somehow, and Berners Lee took up the development of a system for the Internet. In two years of successful work, he created hypertext, or HTTP, the famous electronic HTML language and URL. We don’t need to go into details, because now we see them as regular links for website addresses.
Information space
First of all, this is an information space, access to which is provided through the Internet. It allows the user to have access to data that is located on the servers. If we use a visual-figurative method, then the Internet is a volumetric cylinder, and the World Wide Web is what fills it.
Through a program called a "browser", the user gains access to the Internet to surf the Web. It consists of an innumerable number of sites that are based on servers. They are connected to computers and are responsible for storing, loading, and viewing data.
Spider webs and modern man
Currently, Homo sapiens in developed countries have almost completely integrated with the World Wide Web. We are not talking about our grandparents or about remote villages where they don’t even know about some kind of Internet.
Previously, a person in search of information went straight to the library. And it often happened that the book he needed was not found, then he had to go to other institutions with archives. Now there is no need for such manipulations.
In biology, all species names consist of three words, such as our full name Homo sapiens neanderthalensis. Now we can safely add the fourth word internetiys.
The Internet is capturing the minds of humanity
Agree, we get almost all our information from the Internet. We have tons of information at our fingertips. Tell our ancestor about this, he would eagerly stare at the monitor screen and sit there all his time free time looking for information.
It was the Internet that brought humanity to a fundamentally new level; it contributes to the creation of a new culture - mixed or multi. Representatives of different nations mimic and adapt, as if merging their customs into one cauldron. Where does the final product then come from?
It is especially useful for scientists; there is no longer a need to gather at consultations in a country that is located 1000 km from yours. You can exchange experiences without a personal meeting, for example, through instant messengers or social media. And if important question If we need to discuss it, we can do it via Skype.
Conclusion
The World Wide Web is a component of the Internet. Its operation is ensured thanks to storage servers, which provide information to the user upon request. The Network itself was developed thanks to scientists from the United States and their enthusiasm.
