Computers are popular in our lives.It's hardly to imagine a world without computer.
First of all.Scientists use computers to forecast weather tomorrow.It need 3 years to calculate the result if 100 people are doing the mission rather than one computer's half an hour for the same work.
Second,computers are necessary in banks,communication corporations and governments.
The last.No computers no robots,frequency-changed air conditions or modern movies.Our lives will be drab.
