Дәріс тезисі:

A computer system is, of course, a computer itself with system and application software. In addition, a computer system is a set of devices participating in process of information transferring to a long distance. Such a system is also called a computer network.



If to tell about a computer system as one device (computer), then it is more reasonable to call such a system as a computer network. If to consider a computer system as a set of devices, then one can select:

  • a local computer network as a set of computers limited by a building, office, room;

  • a wide computer network, in which computers are remote from each other and data are connected by wires or wirelessly.

In addition to the mentioned types, it is possible to select the following characteristics for classification of computer networks:

  • as technology (common type of a network displaying physical placement of computer systems in a network and connections between them);

  • as architecture (specification of communication developed for determination of functions of a network and establishment of standards of different models of the computer systems intended for exchange and data processing);

  • as used protocol (a protocol defines a general set of lines and signals, which computers use in a communication network).

The architecture of computer systems consists of the following components:

  • computing and logical opportunities (instruction set, data formats, algorithms of execution of operations);

  • hardware (organization of memory, control, the organization of actions with external devices);

  • software (operating systems, programming systems, application software).
