slide 2

The Internet is a global telecommunications network of information and computing resources. Serves as the physical basis for the World Wide Web. Often referred to as the World Wide Web, the Global Network, or simply the Network.

slide 3

History of the Internet After the Soviet Union launched an artificial Earth satellite in 1957, the US Department of Defense decided that America needed a reliable information transmission system in case of war. Defense Advanced Agency research projects The United States (DARPA) proposed to develop a computer network for this.

slide 4

History of the Internet The computer network was called ARPANET (Advanced Research Projects Agency Network). The first ARPANET server was installed on September 1, 1969 at the University of California, Los Angeles. The Honeywell 516 computer had 12 KB of RAM.

slide 5

History of the Internet By 1971, the first program for sending Email over the network, the program immediately became very popular. In 1973, the first foreign organizations from the UK and Norway, the network has become international.

slide 6

History of the Internet In the 1970s, the network was mainly used to send e-mail, the first lists appeared at the same time. mailing list, newsgroups and bulletin boards. By the end of the 1970s, data transfer protocols began to develop rapidly, which were standardized in 1982-83. Jon Postel played an active role in the development and standardization of network protocols.

Slide 7

History of the Internet On January 1, 1983, the ARPANET switched from NCP to TCP/IP, which has been successfully used to this day to connect networks. It was in 1983 that the term "Internet" was assigned to the ARPANET. IP address - a unique address of a device connected to a local network and (or) the Internet.

Slide 8

History of the Internet In 1984, the domain name system was developed. In 1984, the US National Science Foundation founded the vast intercollegiate network NSFNet, which was made up of smaller networks and had a much larger throughput than ARPANET.

Slide 9

History of the Internet In 1988, the Internet Relay Chat protocol was invented, thanks to which real-time communication (chat) became possible on the Internet.

slide 10

In 1989, in Europe, within the walls of the European Council for Nuclear Research (fr. Conseil Européen pour la Recherche Nucléaire, CERN), the concept of the World Wide Web was born. It was proposed by the famous British scientist Tim Berners, who over the course of two years developed the HTTP protocol, the HTML language, and URIs. History of the Internet

slide 11

In 1990, the ARPANET ceased to exist, completely losing the competition to NSFNet. In the same year, the first connection to the Internet via a telephone line was recorded. History of the Internet

slide 12

In 1995, the World Wide Web became the main provider of information on the Internet, overtaking the FTP file transfer protocol in terms of traffic, and the World Wide Web Consortium (W3C) was formed. Since 1996, the World Wide Web has almost completely replaced the concept of the Internet. History of the Internet

slide 13

In the 1990s, the Internet unified most of the then existing networks. By 1997, there were already about 10 million computers on the Internet, more than 1 million domain names were registered. The Internet has become a very popular medium for information exchange. History of the Internet

What is the Internet? Optional course "Roads of the country Internet" MUNICIPAL GENERAL EDUCATIONAL INSTITUTION SECONDARY EDUCATIONAL SCHOOL 5 ©Epifanova T.N. / academic year


Sooner or later, every person who surfs the Internet asks the question: What is the Internet? The Internet is a normal network. Same as the wiring network in a building, city, country, etc. This is a collection of wires from cheap to very expensive, and sometimes radio and satellite signals. The most important element of this network is that at the ends of each wire is a computer or telephone or some other device of the digital world. The main task of the Internet is to connect and maintain small computer networks, such as those in an office, and create one large one. Information on the Internet - films, music, poems, books, postcards, etc. - appears thanks to users, i.e. those at the ends of this network. The more users, the more information on the Internet. Today, the Internet is the world's repository of information.


The history of the creation of the Internet The Internet began to emerge in 1957 in the United States as a response to the launch of a satellite Soviet Union. It was planned to create a reliable network for the transmission of electronic messages in case of war. The first network was called ARPANET. It brought together four research university centers in the United States. Later, other research centers joined this network. In 1988, the first program appeared that allowed users to exchange text messages in real time. This development was named IRC - chat and is used to this day. The first ARPANET soon had a serious competitor - NSFNet, which worked much faster. In 1990, NSFNet won a landslide victory. World-famous scientific centers connected to it, enriching it with information. The Internet, as it is now, was developed within the walls of the European Council for Nuclear Research. The famous scientist Tim Berners-Lee developed a programming language on which all Internet pages (websites) and a system of addresses connecting computers are created.


Approximate graphic image links between Internet networks The Internet has long become an indispensable part of our lives. It helps us connect with friends around the world and keep up to date with the latest news. You do not need any special knowledge to work on the Internet, you just need to take the first step. Getting to know the Internet



Global computer networks connect local networks and individual computers, their sizes are not limited. An organization is like an organization telephone communication. The user's personal computer is connected to a permanent network node. Nodes are interconnected and this connection is permanent. The figure shows a typical WAN architecture. network nodes - U1, U2 ... user computers - A11, A12 ... gateway - a node connecting computer networks






The World Wide Web and the Internet? The World Wide Web is an association of computer networks, documents on remote computers, programs that allow you to view these documents and maintain communication between them. Internet (pronounced [internet]; English Internet) worldwide system of interconnected computer networks

Fragments from the presentation:

The Internet is a global computer network covering the entire world. Today, the Internet has about 15 million subscribers in more than 176 countries around the world.

The size of the network increases by 7-10% monthly.

On the Internet as of 2002. there were over 150 million servers. Of these, about 400 thousand in Russia.

E-mail is the most common service on the Internet. Approximately 20 million people currently have their email address

Brief historical introduction

About 25 years ago, the US Department of Defense created a network that was the forerunner of the Internet - it was called ARPAnet. ARPAnet was an experimental network - it was created to support scientific research in the military-industrial sphere. In the ARPAnet model, there has always been communication between the source computer and the destination computer (destination station).

Data transmission in the network was organized on the basis of the Internet Protocol - IP. The IP protocol is the rules and description of how a network works. Approximately 10 years after the advent of ARPAnet, Local Area Networks (LANs) appeared, for example, such as Ethernet, etc. At the same time, computers appeared, which began to be called workstations. Most of the workstations had the UNIX Operating System installed. This OS had the ability to work on a network with the Internet Protocol (IP).

One of the most important of these new networks was NSFNET, developed at the initiative of the National Science Foundation (NSF), a counterpart to our Department of Science. In the late 80s, NSF created five supercomputing centers, making them available for use in any scientific institution.

In 1983, the first standard for TCP/IP protocols was released. After some time, TCP / IP was adapted into a common, that is, a public standard, and the term Internet came into general use.

In 1991, the ARPANET ceased to exist, the Internet exists, its size is much larger than the original, as it connected many networks around the world.

The Internet is all networks that, interacting using the IP protocol, form a "seamless" network for their collective users. This includes various federal networks, a set of regional networks, university networks and some foreign networks.

In fact, the Internet consists of many local and global networks.

Who controls the Internet?

The Internet Society, or ISOC (Internet Society), determines the direction of the Internet. ISOC is a voluntary organization whose purpose is to promote the global exchange of information through the Internet.

She appoints a council of elders that is responsible for the technical direction and direction of the Internet.

The IAB Board of Elders (Internet Architecture Board or Internet Architecture Board) is a group of invited individuals who have volunteered to take part in its work.

The IAB meets regularly to approve standards and allocate resources (eg addresses). The Internet works by having standard ways for computers and applications to communicate with each other.

Internet users express their opinions at IETF (Internet Engineering Task Force) engineering committee meetings. IETF is another public body; it meets regularly to discuss the current technical and organizational problems of the Internet.

Internet Protocol (IP)

With the help of communication lines, data is delivered from one point to another. How does this happen?

Different sections of the Internet communicate through a system of computers (called routers) that interconnect networks. These can be Internet networks, networks with marker access, telephone lines.

Routers are mail substations; they make decisions about where to send data ("packets") The router looks at where your data is addressed and decides where to send it.

Searching for information on the Internet

The saturation of the Internet with Web-documents is enormous. Search necessary information- the main problem of the WWW service. It is solved with the help of hyperlink technology. There are special Web - sites that are called search engines or search directories. For example:

Nowadays, there are specialized search engines on the Internet to search for information that can search many directories at once. By which the user determines himself.

Examples are:

  • Russian search engineAdClick
  • Aport search engine
  • yahoo link directory.

We present to the attention of the visitors of the portal a new section: Presentations on the topic of the Internet. Why is there such a need to collect all the material in one place? Just to make it convenient for network users to download a presentation on the Internet, the global computer network and the World Wide Web on one service, which they liked or needed to prepare for lessons, class hours, or just to get acquainted with interesting information.

The Internet is now actively entering the life of modern families and is becoming an integral part of the life of almost every child. Internet access has opened up great opportunities for interesting information, chatting with friends. Often it becomes a tool that cripples the life and psyche of not only teenagers, but also younger schoolchildren who sit for hours in in social networks or day after day they endlessly play games that zombify the psyche. It is unlikely that parents will be able to explain to the child the whole truth about this powerful global network, so the presentation "Internet - Global Computer Network" should reveal to children the whole truth about that modern miracle.

Many parents and teachers ask at what age children should be taught about the Internet powerpoint presentation? It is possible in any, if they have already begun to show interest in the network, the main thing is that the information on the slides is accessible to the understanding of the child.

On our portal, you are offered not one presentation on the Internet and the World Wide Web for grades 9-10, but a whole collection of materials that will be useful to children of different ages and will arouse interest in a teacher who is preparing for class hour Or a computer science class.

Download the Powerpoint presentation on the topic "Internet in Russia and the global computer network" we offer only for free. To do this, you do not need to enter any codes or register, advertise us on social networks or pay for the material provided. We explain how to download a presentation from the Internet about computer or global networks through our portal: just follow the link and save all the material on your computer. Use the collected presentations about its power of the Internet, and we will upload for our visitors new developments for class hours and computer science lessons.
