What is the Internet? Optional course “Roads of the Internet Country” MUNICIPAL EDUCATIONAL INSTITUTION SECONDARY EDUCATIONAL SCHOOL 5 ©Epifanova T.N. / academic year

Sooner or later, every person surfing the Internet asks the question: What is the Internet? The Internet is a regular network. The same as the electrical wiring network in a building, city, country, etc. This is a collection of wires ranging 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 there 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, for example, such as in an office, and create one large one. Information on the Internet - films, music, poetry, books, postcards, etc. - appears thanks to users, i.e. to those at the ends of this network. The more users, the more information there is on the Internet. Today, the Internet is a worldwide repository of information.

History of the Internet The Internet began to emerge in 1957 in the United States as a response to the launch of Sputnik by the Soviet Union. The plan was to create a reliable network for transmitting electronic messages in case of war. The first network was called ARPANET. It united four US university research centers. Later, other scientific 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 still used today. The first ARPANET soon had a serious competitor - the NSFNet network, which worked much faster. In 1990, NSFNet won a landslide victory. World-famous scientific centers connected to it, enriching it with information. The Internet in its present form was developed within the walls of the European Council for Nuclear Research. The famous scientist Tim Berners-Lee developed a programming language in which all Internet pages (sites) and a system of addresses connecting computers are created.

An approximate graphical representation of the connections between Internet networks The Internet has long become an indispensable part of our lives. It helps us communicate with friends around the world and stay updated with the latest news. You don't 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. The organization is similar to the organization of telephone communications. The user's personal computer is connected to a permanent network node. The nodes are connected to each other and this connection is constant. The figure shows the typical architecture of a global network. network nodes - U1, U2 ... user computers - A11, A12 ... gateway - a node connecting computer networks

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

Slide 1

THE IMPACT FOR THE CREATION OF THE INTERNET WAS THE LAUNCH OF THE FIRST ARTIFICIAL SATELLITE IN THE SOVIET UNION IN 1957, IN WHICH THE UNITED STATES SAW THE THREAT OF USING MISSILES TO CARRY NUCLEAR STRIKES ON THE USA

History of Internet development

Slide 2

ARPA Research Projects Agency

In the same 1957, the Research Projects Agency - ARPA - was created under the US Department of Defense. Scientists were tasked with creating a computer network that could be used by the military during a nuclear attack on the country. The network was to be used to communicate between command posts of the defense system.

Slide 3

Main criterion

The main criterion when creating the network was considered to be the invulnerability of the network during a nuclear attack, even if some branches and nodes were destroyed, and it was also necessary to take into account issues of the secrecy of information transmitted over the network. To fulfill this condition, in 1962, Paul Baren's network concept was proposed, based on two main ideas: 1) the absence of a central computer - all computers on the network have equal rights; 2) a batch method of transferring files over the network.

Slide 4

The concept of the "Galactic Network"

Another theoretical source for creating a network was the concept of the “Galactic Network” by Joseph Licklider, who became the director of a computer program for creating a network in 1962.

Slide 5

In 1966, the creation of the Arpanet computer network began.

In October 1967, it was decided to use the concepts of P. Baren and J. Licklider to create Arpanet. From October to December 1969, four US university centers - the University of California Los Angeles, the University of California Santa Barbara, the Stanford Research Institute and the University of Utah - were united into one network.

Slide 6

Year of birth Internet

1969 is considered the year of the birth of the Internet, since subsequent events showed that the Arpanet network became the basis of the Internet.

Slide 7

Public organization INWG

In 1972, the public organization INWG was created - a working group on international networks, under the leadership of Vincent Cerf. The INWG coordinated the work to create the internetworking capability.

Slide 8

Merging TCP and IP

To combine networks running on the IP protocol and networks running on other protocols, it was necessary to create a special internetworking protocol. This protocol was created by Vincent Cerf and Robert Kahn in 1974 and named TCP. After the two protocols TCP and IP were combined into one in 1982, TCP/IP became the standard protocol for the Internet.

Slide 9

"Father of the Internet"

That same year, Surf and his colleagues coined the term “Internet.” Today Vincent Cerf is called the "Father of the Internet."

Slide 10

Russia and the Internet

Russia first gained access to the Internet in the early 80s. Access was provided by the Institute of Atomic Energy named after. I.V.Kurchatova. In 1990, RELCOM, a network of UNIX users, was created.

Slide 11

Internet

The largest global network, covering almost all countries of the world, is the Internet computer network. This term appeared in 1982. Literally translated into Russian, the Internet is an “internetwork,” i.e., it is an association of networks. The Internet is a worldwide information network. Sometimes the Internet is simply and respectfully called the Network. This area of computer technology is now rapidly developing.

Slide 12

The history of the Internet can be divided into Stages:

1945-1960 Theoretical work on interactive interaction between man and machine; the emergence of the first interactive devices and computers that implement time sharing mode; 1961-1970 Development of technical principles of packet switching, implementation of ARPANet; 1971-1980 The number of ARPANet nodes increased to several dozen; special cable lines have been laid connecting some nodes; e-mail begins to function; Scientists report on the results of their work at international scientific conferences; 1981-1990 TCP/IP protocol adopted. The US Department of Defense decides to build its own network based on ARPANet, a division into ARPANet and MILNet occurs, the Domain Name System (DNS) is introduced, the number of hosts reaches 100,000; 1991-2008 Recent history

Presentation on computer science on the topic "Internet". As written, made in 2007. Author: Oberyomko V.A. Contains a fairly detailed history of the creation of the Internet. Lots of text and as many as 21 slides.

The presentation currently contains outdated information in places; the Internet has managed to step forward. Therefore, it requires improvement. If you have better presentation options, we will be grateful if you send them to this email address: we will definitely post them.

Internet - World Wide Web

Answering her alarm on Friday morning, Stacey gets out of bed. At the same time, objects in her house begin to prepare for the day. Even though it's dark outside, the interior is lit with the tones of a beautiful sunrise, based on Stacy's custom lighting scheme. The water heater ensures that the shower will suit her preferences. When she enters the bathroom, her movement begins to drink coffee and microwave breakfast.

Since Stacy eats breakfast, her calories are controlled. Morning headlines and stories are projected onto the wall next to the desk. A green light says every device in the house is working perfectly, although she would have been notified before anything came close to failing and a repair order would have been automatically issued. The display lets her know that her commute to work today will take 37 minutes on an alternate route due to heavier-than-usual traffic on her regular route.

Excerpts from the presentation:

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

The network size increases monthly by 7-10%.

On the Internet according to data for 2002. there were over 150 million servers. Of these, about 400 thousand are in Russia.

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

Brief historical introduction

Before Stacy leaves, she thinks about dinner. The display says she needs to have chicken today or it might go bad. Her phone beeps and tells her the grill needs to fill its propane tank. She presses "auto" to arrange for the fastest delivery of the refill based on when her schedule indicates she will be home and able to accommodate the delivery.

Stacy gets into her car, which has already been brought to the ideal internal temperature. The vehicle automatically exits its driveway into the first available gap in traffic. According to the vehicle's reading, her trip today will cost more than usual due to congestion on the alternate route. She realizes that she could have avoided additional fees by leaving a little earlier.

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 was always communication between the source computer and the destination computer (destination station).

When Stacy arrives at work, she glances at her large office display and sees that all plant processes are functioning normally. With the exception of the autonomous car, all of the core capabilities described above exist today and are part of the Internet of Things. However, software and services to aggregate and manage discrete capabilities do not yet exist to make them commercially available.

Definition of the Internet of Things. Internet of Things is simply a concept in which machines and everyday objects are connected via the Internet. The depth and variety of Internet things. Not long ago, devices on the Internet had to be connected to a fixed location.

Data transmission on the network was organized based on the Internet protocol - IP. The IP protocol is the rules and description of how a network operates. About 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 workstations had the UNIX Operating System installed. This OS had the ability to work on a network with the Internet Protocol (IP).

While cars may not yet be autonomous, new models have a host of internet-connected capabilities, including remote start, remote climate control, location tracking, and the currently hidden ability to track many of your driving habits. Each time you hear a beep, another piece of data is recorded.

Display all data and video. Research is currently underway to directly communicate with your visual cortex and auditory brain. After a day of work, Stacy comes home and wants to get some exercise. A glance at her phone tells her that during the day she consumed more than 700 calories than her Fitbit recorded her burning. When she gets on her treadmill, she automatically but safely starts her workout. Her phone beeps to remind her that her son is swimming at Oahu's North Shore.

One of the most important of these new networks was NSFNET, developed at the initiative of the National Science Foundation (NSF), our equivalent of the Department of Science. In the late 1980s, NSF created five supercomputing centers, making them available for use in any scientific institution.

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

Open water floats in 15 minutes. She really wants to watch it live, so she activates her app, which allows her to film almost anything, anywhere at any time. She films and sends the camera-equipped drone from the depot to Oahu and gives it the coordinates for the sailing course. The live image from the drone is projected onto a nearby wall.

She puts everything in her house on "unoccupied" status and clears her calendar. The last two operations were pre-configured and triggered by a single message. What are the consequences of Internet broadcasting? The benefits based solely on the products that exist today, not to mention the unimaginable combinations of new capabilities, are enormous. More than ever, the smartphone has become the remote control for life. Data is available at your fingertips on everything you can imagine. But there are still many problems and failures ahead.

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

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

These challenges include technical issues, business issues, requirements for new and developing skill sets, legal and regulatory challenges, and social complexities. Blogs separated individual articles from full newspapers. The last thirty years have seen a pattern of aggregation, followed by division, and then re-aggregation.

The next level includes entirely new aggregated products and systems that connect these devices in new ways, such as home control systems. The third tier, and by far the largest and fastest growing, consists of all services that provide customized solutions for businesses and consumers. Business models are shifting from selling single products to recurring revenue models. Products and kits can be remotely reconfigured and quickly repaired. Customers can be provided with tools for self-reconfiguration.

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

Who controls the Internet?

The direction of Internet development is mainly determined by the Internet Society, or ISOC (Internet Society). ISOC is a voluntary organization whose purpose is to promote global information exchange via the Internet.

She appoints a council of elders who are responsible for the technical direction and guidance of the Internet.

Ultimately, adaptive systems will reconfigure themselves to customer needs. Agile businesses that can customize and personalize their products to their customers' immediate needs have a strong advantage. Insurance problems and opportunities; for example, autonomous cars, but data will also facilitate risk assessment; possibility of new pricing models: customization of insurance premium based on health and driving data.

Who controls the Internet?

The Internet of Things is changing government. Parking fees vary depending on the block, time of day and day of the week. A new era of congestion pricing is opening for state highways. Each device is capable of generating huge amounts of data that must be stored, protected and analyzed. Users will provide personalized data feeds to more than 100 apps and services every day. It is important for companies to understand these application and data flows and be able to identify bottlenecks.

The IAB (Internet Architecture Board) is a group of invited individuals who volunteer to participate in its work.

The IAB meets regularly to approve standards and allocate resources (such as addresses). The Internet works because there are standard ways for computers and applications to communicate with each other.

The supply of mobile sensors and controllers is a challenge. Batteries need to be small but still provide a useful life between charges. The massive target disruption was caused by a heating, ventilation and air conditioning company. Theft of personal and corporate data is bad enough, but the prospect of hacking into life support systems and even embedded medical devices is life-threatening.

How can you prepare? These skills include network design, data analysis, data security, and engineering. The Internet is a huge network of millions of computers connected all over the world that can communicate with each other. The Internet has caused a revolution in business. There is no longer a requirement for personnel to actually be present to perform this work. Any work can be done almost using the Internet. The Internet has removed the distance between countries and continents.

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

Internet Protocol (IP)

Communication lines ensure the delivery of data from one point to another. How does this happen?

Different parts of the Internet communicate using a system of computers (called routers) that connect networks to each other. These can be Internet networks, token access networks, telephone lines.

Routers are postal 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.

Global Internet

Financial institutions, stock markets, investment banking, aviation, hospitality, railways, software firms operate efficiently using the Internet. They make the most impressive and professional presentations to their stakeholders using our online presentation templates.

Electronic mail: electronic messages about everyday life around the world File Transfer Protocol. Terminal emulation. Summary This paper should give internet newbies a brief and concise overview of the internet.

Searching for information on the Internet

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

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

Introduction No other industry has seen such growth in recent years as computer networking. And among them again is the Internet, which has surpassed all others in size. Global subscriber numbers are estimated at approximately 40 million. Thus, it has reached the same size as critical mass: a chain reaction has begun, and this process inexorably reaches new dimensions. The Internet and its successors will change our lives significantly in the next few years, since television was once invented, almost 50% of all German Internet users believe.

Examples include:

INTERNET. Story. Connection methods Poplavskaya Olesya Vladimirovna, MBOSHI "Technical Lyceum-Boarding School" 128 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, Global Network, or simply the Network.

On the other hand, the dissemination of knowledge about the functioning, purpose and purpose of this network has not been able to fully track the growth rate. There is a clear need to catch up here in the German-speaking area. Although American literature on the Internet is rich, it describes a network of local conditions that differ significantly from those found in this country. So the timing for this script was right. This script is a summary of several reports published electronically over the Internet.

Report on the results of a three-week online survey. Unpublished publication, casting. The Internet is the largest computer network in the world and the only real highway or information superhighway in existence. This is the name of a group of information and communication systems distributed throughout the world. The size and complexity of these systems is beyond human imagination - it is more than a computer network - it is a social entity with its own culture. In technical terms, the Internet is a network of computers that communicate with each other according to a specific protocol, the Internet Protocol.

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

History of the Internet The computer network was named 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.

History of the Internet By 1971, the first program for sending email over the network was developed, and the program immediately became very popular. In 1973, the first foreign organizations from Great Britain and Norway were connected to the network via a transatlantic telephone cable, and the network became international.

History of the Internet In the 1970s, the Internet was primarily used for sending email, and the first mailing lists, news groups, and bulletin boards appeared at that time. 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.

History of the Internet On January 1, 1983, the ARPANET switched from the NCP protocol to TCP/IP, which is still successfully used to connect networks. It was in 1983 that the term “Internet” was assigned to the ARPANET network. IP address is a unique address of a device connected to a local network and (or) the Internet.

History of the Internet In 1984, the domain name system was developed. In 1984, the US National Science Foundation founded an extensive inter-university network, NSFNet, which was made up of smaller networks and had much greater capacity than ARPANET.

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

In 1989, in Europe, within the walls of the European Council for Nuclear Research (French 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, within two years, developed the HTTP protocol, the HTML language and URIs. History of the Internet

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

In 1995, the World Wide Web became the primary provider of information on the Internet, overtaking the FTP file transfer protocol in 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

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

Internet connection Currently, you can connect to the Internet through: communication satellites, radio channels, cable television, telephone, cellular communications, special fiber-optic lines or electrical wires.

Internet connection Wireless Internet connection (Wi-Fi): Today, anyone with a laptop with wireless connectivity can appreciate the convenience of Wi-Fi. A wireless Wi-Fi network allows several users to simultaneously access the Internet and use various network and Wi-Fi devices.

Internet connection Connecting and setting up STREAM (ADSL): STREAM is the Internet that comes to you via telephone wires, but leaves your phone free for calls (ADSL technology). Today, STREAM is one of the optimal ways to connect to the Internet for most clients.

We present to the attention of portal visitors a new section: Presentations on the Internet. Why was 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 need to prepare for lessons, class hours, or just to get acquainted with interesting information.

The Internet today is actively entering the lives of modern families and becoming an integral part of the life of almost every child. Access to the Internet has opened up great opportunities for obtaining interesting information and communicating with friends. Often it becomes a tool that cripples the lives and psyche of not only teenagers, but also younger schoolchildren who spend hours on social networks or endlessly play games that zombify the psyche day after day. It is unlikely that parents will be able to explain to their child the whole truth about this powerful global network, so the presentation “The Internet - a global computer network” should reveal to children the whole truth about that modern miracle.

Many parents and teachers ask at what age should children be shown a Powerpoint presentation about the Internet? You can do it at any time, if they have already begun to show interest in the Internet, the main thing is that the information on the slides is accessible to the child’s understanding.

On our portal you are offered not just one presentation on the topic of 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 the interest of a teacher who is preparing for a class hour or computer science lesson.

We offer to download the Powerpoint presentation on the topic “The Internet in Russia and the global computer network” only for free. To do this, you don’t 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 on the Internet, and we will upload new developments for classroom hours and computer science lessons for our visitors. Perhaps very soon one of the site’s visitors will be able to make a presentation on the Internet for free online, create their own website and become famous thanks to the enormous possibilities of the global network.

Excerpts from the presentation:

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