What are computers?
Computers are wonderful
machines. They can store information and solve problems.
Computers come in all sizes.
Some are small enough to fit into our ; others are so big that the can fill.
Some people say that computers
can think themselves. This is not true. Human beings give computers
instructions and tell them.
However, computers can do
things better than people. They can store information and never forget it. They
work out difficult problems very, very quickly-usuallythan any human being.
You may have used computers
such as a pocket calculator, or
a personal computer. If not, why not learnright away？
