The system block

 

   The processor. At a choice of the processor it is necessary to pay attention to the characteristics connected to his(its) opportunities and the speed of work.

  The most important parameter of speed of the processor is clock frequency. She(it) is measured in megahertz and shows, how many instructions the processor can execute during a second. She(it) in figure is designated in the name of the processor. For example, Pentium 4-2000, has clock frequency in 2000 MHz.

  Each generation of processors differs from each other new opportunities, in the speed of work, workmanship of the work and appearance. In each generation are available also updatings. For example, in main family Pentium 4 three are registered: Extreme Edition; Pentium 4; Celeron D. For a house last, as a rule, serves. Also three updatings enter in competing with Intel family AMD. It Athlon 64, Athlon XP and updating Sempron (the cut down version).

  Frequency of the system trunk - the important factor of work of a computer. The trunk is a hardware highway on which the data run, from the device to the device. The above frequency of the trunk, the more than the data can act(arrive) for a time unit in the processor. With change and updating of interiors of the processor (change such as a nucleus, the locations of  «internal bodies »), varies also appearance of the computer block.

   It is better than what mark the processor: Intel or AMD? It is a question at issue. All depends on what you from him(it) want. Computers from AMD, differ good abilities in work from multimedia and games. But nevertheless more reliable on former count computers from Intel.
