DEVELOPMENT OF COMPUTER NETWORKS

Computer network is a complex of territorially dispersed computers interconnected by data links. Computer networks represent a complex of technical, program and information means. From a technical point of view a computer network is a system for transmitting data, consisting of a set of terminals and the communication environment. Terminals (workstations) are final devices at the ends of a computer network which send or receive information in relation to the other terminal. The communication environment serves for transmitting data between terminals, consists of channels (nodes).

From the beginning, computer networks were created by a principle: some computers with network adapters consistently connected by coaxial cable. Further development of computer networks began to occur on the principles of structuring. Each computer network consists of a set of interconnected parts - structures. Each separate structure represents some computers with network adapters, each of which is connected to the commutator by separate wire (twisted pair).

The connection of computer networks in various organizations caused emergence of a special equipment, for example, hubs (host united blocks), bridges, routers, concentrators, which are carrying out such interaction. When you connect your computer to the hub, a part of electronics of a network interface is in the computer, and a part of it is in the hub. Bridges and hubs are used to connect to your computer. Routers are used for the organization of traffic, they convert data from one format to another, and also organize a protection of information.

Three the most effective network services are provided for subscribers of a computer network:

- providing information on all areas of human activity;

- electronic communications: e-mail – transmission and reception of a text and graphic information; teleconferences – an exchange of information between participating users;

- a remote execution of programs: this is a service of the Internet, the user receives the unique name connecting to the network, and his computer becomes a network station.
