We think with our head. But can computers think?
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.
They can get the information from the outside. And the monitor and printer are like a man's hands and
mouth. They can send the information to the outside after the head-CPU thinks about it.
We often use a computer. We use the keyboard and the mouse to give a computer some information.
Then the computer sends the information to CPU. After CPU thinks about it, the computer gives the
result (结果) to the monitor. Then we can see it!
