Central Processing Unit The processing unit or the Central Processing Unit is responsible for carrying out The processing job. The CPU is the 'brain' of the computer. It is where all the searching, sorting, calculating and decision making take place. The CPU is the control center for a computer. It guides, directs and controls a computer's performance. The CPU is a single large scale semiconductor circuit chip and is also known as the microprocessor. It can be represented by a simple diagram as shown below The processor is placed and secured into a compatible CPU socket found on the motherboard. Processors produce heat, so they are covered with a heat sink to keep them cool and running smoothly. As you can see in the above picture, the chip are hundreds of connector pins that plug into each of the corresponding holes in the socket. Today, most CPU's resemble the picture shown above. However, Intel and AMD have also experimented with slot proces...
