     Does a computer have a head? We can use a computer to calculate, play games, send emails, do

 homework and other things. A computer has several parts.

     Which part is the head of the computer? In the main part of the computer, there is an element (元件)

 called CPU. That's the head of a computer. The keyboard and mouse are like a man's eyes and ears.

 mouth. They can send the information to the outside after the head-CPU thinks about it.
