INTERNET - the largest and most popular network in the world, which connects millions of computers into one giant network, providing unlimited access to information and communication in different ways.

INTERNET The word literally means international network (INTER-national NET-work)

The Internet was born in the United States in the 1960s. It was invented by the CIA to keep in touch with computer networks connected to each other by telephone in the event of a war. During the successful experiment, the ARPAnet network emerged, which connected only three computers at research centers in California and Utah. Later, ARPAnet served a peaceful purpose, it was mainly used by scientists and specialists. In the early eighties, the term Internet appeared. This is the English word for international network.

The Internet is distributed in 3 directions:

•       technical or hardware component;

•       software component;

•       information component.

Hardware component

It consists of different models and systems of computers, communication channels with different physical bases, mechanical and electrical devices between computers and communication channels.

Software component

Provides compatible operation of different types of computers and devices on the Internet. Its main functions are:

- storage, retrieval, collection, initial restoration of information;

-security of information in the network;

- ensuring the functional compatibility of the equipment.

Software is divided into two groups (classes):

- server programs are located on the network node (host computer) that serves the customer's computer;

- client programs, located on the customer's computer and use the services of the server.

Information component

The information component is represented by various documents stored on computers on the network. Online documents are transmitted to each other via reference addresses.
