Computer Architecture

Contemporary computers put the ALU and control units into a single integrated circuit known as the Central Processing Unit or CPU. Typically, computer memory is placed on top of a small number of integrated circuits near the CPU. Tools that occupies most of the space in the computer is ancilliary system (for example, to provide electricity) or device I / O.

Some larger computers differ from the above model on the one main thing - they have multiple CPUs and control units working simultaneously. Moreover, several computers, used largely for research purposes and scientific perkomputeran, have differed significantly from the model above, but they have found little commercial use.

The function of the computer is actually quite simple in principle. Computer reaching the command and data from memory. Command performed, the results are stored, and subsequent orders achieved. This procedure is repeated until the computer is turned off.
