Computers have become so necessary to modern living that it is difficult to believe that they are a relatively recent invention. We cannot live without computers, as they are involved in most of the everyday options. It’s really hard to imagine a life without computers.

In schools, students use computers to learn and teachers use computer in their teachings. All they need to do is just sit in front of the monitor and click the mouse. That means computers make the learning and teaching processes more efficient. As a result, students are all better educated. Although some people may complain students of becoming less concentrated on the lessons if computers are used, it is not the problem of using computers. That is the problem of the students’ behaviours. We cannot blame the computers, as it is the responsibility of students.

In offices, businessmen use computers to trade with other companies, especially those who are overseas. They can communicate with each other in a short time. Thus, trades can be finished in a more efficient way. Besides, they can collect the most up-to-date financial information from the Internet so that they can make the best decision. Moreover, computers are used to control the operation of machines. Therefore, the productivity of companies can be highly increased. According to a survey report, the computer-related medical claims had a 5% increase within the last two years, therefore it suggested us not to use computers in offices. However, illnesses are brought by the inappropriate computer-aid working facilities. Illnesses can be combated by using ergonomic desks or chairs.

In transportations, computers are used to control trains, ships and even the planes. The use of computers makes the itinerary more steady and safe. Since these computer systems are very reliable, pressures of the divers can be reduced. On the other hand, computers are used to control the traffic lights. They can accurately assign time for pedestrians and vehicles. They contribute to our transport system. It is believed that computer system may be out of order, and unreliable. We should not rely on them too much. It may be true to a certain extent. However the convenience that computer brought to us cannot be neglected. Also they rarely become out of order. Since the convenience out weight the problems, computers still bring us more benefits.
