As far as I am concerned,the computer is the greatest invention so farhine.The oldest kind of computer is the abacus,used in China many centuries ago,but the first large and modern computer was invented in 1946.The computer could work out maths problems quite fast.
Now the computers are getting smaller and smaller,and computing faster and faster.Many scientists agree that computers can now do many things,but they cannot do everything.Who knows what the computers tomorrow will be like?Will computers bring good things or bad things to people?The scientists today have to decide how to use the computers tomorrow.
So computers do considerably good to our life.
