My view on computer
Computers are playing a more and more important role in modern society.They are widely used almost in every field,such as business,transportation and education.We use computers to process and store all kinds of information.Also,they are entering ordinary families.We use computers to control electrical appliances and entertain ourselves by playing games on them.Without computers,the world would not be what it is today.
Despite this,computers cause trouble.For instance,a great system will be broken down when only a single computer goes wrong.It is possible that somebody breaks into a computer system to steal secret information.We can not rely so much on computers.
So we should develop more advanced and reliable computers in order to make our life more colorful and meaningful.
