In recent years, the computers using widely  is so considerably obvious that  it affects our daily life impressively. So some people hold the idea that the role which the computers are playing in our lives is extraordinarily significant due to its' capability of making our life  more comfortable. Nevertheless, other people is opposite to them. From their standpoints, the function of using computers is nagative. Though there are one or two disadvantages of computer using remarkble, the computer dose far more good than harm to people in my own opinion.
The first reason I want to put forward is that our lifestyles have become more efficient as a result of using computer adequately widely. For example, we can get an enormous amount of knowledges which is unable to find in the books through the Internet. Through combining  knowledges which are acquired from the classroom with other knowledges which belong to the Internet,then accumulate that kind of knowledges, we are undeniable to understand the world impressively comprehensively. In the meantime, computers provides an opportunity to communicate with capable brains of society so that we have an access to understand things impressively deeply. Since now we all spend tremendous hours every day on working or learning hard that is due to the inreasing rapid pace of society development, we have no choice to leave a little of time for getting together with our family numbers. However, through chatting with parents online, we enable to attain situation about our parents and relatives while we are taking a break after undoubtedly hard work. Without worrying about our parents, it is beneficial to stimulate us to put overall our enthusiasms to work efficiently.
The second reason to prove the remarkable importance of computer is that world have become undoubtedly safer and easier than before when computers are not using widely adequtaly. From my own experiment, some foreigners always have problems to find the corrrect direction available to supermarkets or anywhere owing to  they have not adequate knowledges about local condition. Nonetheless, as long as they surf the internet before going outdoor, there is uncommonly no probablity of losing their way.What is more, computers can put a large number of useful knowledges which are essential for us to come up with the pace of society, which is one of notable advantages compared with newspapers and broadcasting programs. It is through the internet that people who are seeking jobs approach to the information written in the companies website. Have a impressive knowledge of acquirement about jobs, they can make preparations adequately which brings benefits to make considerable expressions during first meeting.  
However,the disadvantages can not easily be left out even though the immense benefits lie in using computers.One of the shortcomings is that viruses have an access to enter our computers when we are surfing internet. Our computers will be out ouf controll so that our private information will be lost via transmitting viruses. What is worse, people have realized that because of computers bringing conveniences to us the number of lazy individuals is on the rise.
From what we have discussed above, it can be clearly concluded that it is more essential to use computers widely to make our lives more convenient and comfortable. Though they have several disadvantages, the advantages can not be left out.
