Can you tell the name of the big-large box beside your computer monitor? Many of call it "CPU". But actually it is the casing, inside which the CPU (Central Processing Unit) is located. Inside the casing, there are several parts. The "brain" of computer is the processor. The "heart" of computer is the main memory. Others than these two main parts, there are several other devices such as hard-disk, CD drive, DVD drive, SMPS etc. All these stuffs are organised in a large board, called Mother Board.
