Has computer made life easier? The information technology has developed so fast that computers, which were completely unknown decades ago, have stepped into almost every household in the world and brought deep impact to the way people work, live and entertain However, like the saying goesevery coin has two sides, computers have also brought some trouble to people As far as work and business are concerned, computers have brought revolutionary change to our traditional practices It greatly increases the efficiency and effectiveness of our work and it is also due to them that E-commerce; E-banking is made available For example, because of them, there is no need for you to queue in the shopping mall as the shopping cart and goods are just one click away in front of you What is more about computer is that it makes possible to two or more things at one time You could communicate with your friends and shopping or playing games or watching movies simultaneously However, computers have a lot of disadvantages which we shall consider First, they are machines which are not infallible Virus could easily spread out through computers and cause chaos, which destroys all the data which has been stored in them or make some fatal mistakes to business or work Secondly, though E-commerce facilitates our life, computers encourage credit fraud or ID fraud, which means someone else could pretend our identity and the machine could not differentiate Last but not least, we have no control over the content on computers, which might expose unhealthy content to children and seriously affect their development Though discussed above, I hold the idea that the advantages brought by computers far outweigh their disadvantages As long as we could use them wisely, like control certain website to be browsed to children, use anti-virus protection and encryption code, we could make them useful to the greatest advantage of human kind
