Personal computer main and modular device The tire of data - the tire for data transmission between various devices. The address tire - the tire for a choice of the device or a memory cell where are sent or from where data on the tire of data are read out. The management tire - the tire for the signaling, defining nature of exchange of information on the highway.

Processor The processor – the device carrying out data processing and operating the personal computer. Main characteristics of the processor: Clock frequency – quantity of steps in a second. Word length – quantity of bits which can be transferred or be processed by the processor at the same time. Productivity – the speed of performance of certain operations in any program environment.

Слайд 7

Maternal (system) payment The main hardware component of the computer is the motherboard. On the motherboard the highway of exchange of information is realized, there are sockets for installation of the processor and random access memory, and also slots for installation of controlers of external devices.
