The computer is the main device. IBM computer is the main device to the following to enter: the system block, monitor and keyboard (the mouse with). The system block is the central processor, operational (operational) memory, a hard disk, the kontroller, disektalar and lezerli compact discs with work to devices and others places.
The central processor. The computer is the most important part of the central processor, (i.e. the processor and control of the device) organization is. The program using the given data transforms, all calculation processes for managing and calculating the work to the relevant devices in the mutual relations of the set device – processor is called. The processor function arifmetik and logical steps complete, the memory to appeal to, in the program of instructions a given sequence of performance management and other steps are complete will be considered.
Mikroprotsessor. Mikroprotsessor big the e - scheme if it is, all the calculations it performs, the information is re - used, program functioning, and ensures and the computer, other device , the work manages. It is the computer's processing speed allows. IBM RS computer usually Intel firm and to him , according to other firms in the mikroprotsessor is set. Operational memory at on the computer by working programs and data stores. The data in permanent memory from the operational to the memory ko’chiriladi, obtained the results needed are in case in the drive and re - written. The computer o’chirilishi with operative in the memory data will be deleted. This memory has two parts consist of toe’ladi. 1-part of the operating system and applied software for the mo’was ljallab. 2-part external memory toe’become, service for used. Hard drive (vinchester) computer with a working that is used the information is constant to keep mo’was ljallab.
The input-output ports through which the processor external devices with information exchange. Internal devices with data exchange for special port and the common port, there is.
3. Personal computers supply and its types
As it is known, information technology, human activity all jabxalarga into go to the process let's go towards advancing and deepening has been.
Total number, ko’p hundred million increased gone, wide spread personal pc in addition, computing system special tools also ko’payib has been. Computers and information systems - let's go towards “do’in ston” toe’become has, and even them computer science in the field of experts toe’who lmas people to also accessible toe’become has. This thing, most primarily the user and the computer programs, with special (systemic) software supply – operating the system through the communication of the termination to make only they come.
Personal computer three major parts are composed, these technical supply (hardware) and software maintenance (software) and a logical supply (brainware)s.
