CPU Guide
The CPU or Central Processing Unit is the brains behind any computer system. Without the processor, the computer simply can't do anything at all. The processor transfers data to the other components of the computer via the system bus. This "Bus" is the physical wires used to send and receive data to each part and is located on the motherboard.
The processor accepts input, processes data,and provides output. The data must be stored temporarily or permanently and the computer's RAM memory becomes very important. The importance of RAM becomes apparent when you know just how the processor chip handles instructions. As these chips becomes becomes faster and faster, the ram memory must also keep up with the development and thus, become much faster as well.
Remember to be sure that the chip you buy is compatible with your system and ask if you can return the chip if there are any problems. Be sure that the upgrade will perform what you want it to do. Your computer's performance will improve with a processor upgrade but you may need to add more ram if you want to improve your Windows programs.
