The study of new material.

So, the topic of our lesson: "The global Internet".

In the lesson we will get acquainted with the global computer network Internet from various sides, get acquainted with the search engines and learn to look for the information we need. The world has really changed with the advent of the global computer network Internet. Today, without leaving your home, you can meet and talk with people who are far away from your country, purchase various goods and services, and much more.

The history of the Internet.

In 1969, the ARPAnet computer network was created in the United States, combining the computer centers of the Ministry of Defense and a number of academic organizations. This network was designed for a narrow purpose: mainly to study how to maintain communication in the event of a nuclear attack and to help researchers in the exchange of information. As this network grew, many other networks were created and developed. Even before the era of personal computers, the creators of ARPAnet began to develop the program Internetting Project ("Networking Project"). The success of this project led to the following results. Firstly, the largest internet network in the USA (with the lowercase letter i) was created.

Secondly, various options for the interaction of this network with a number of other US networks were tested. This created the prerequisites for the successful integration of many networks into a single global network. This “network of networks” is now everywhere referred to as the Internet (Russian publications widely use Russian-language spelling - the Internet).

Currently, tens of millions of computers connected to the Internet store a huge amount of information (hundreds of millions of files, documents, etc.) and hundreds of millions of people use the information services of the global network.
