write about advantages and disavantages of computer

I think this is an interesting topic when I am indeliberate in surfing some webs. And I wonder why no one discusses this????. So, I am eager to make the first writing. Nowadays, most people know to use the computer. But what purposes they use it for ?. that 's why we really recognize that it is so bad or good to use computer. You know, up to the ages, we classify the benefits of computer are. People who work in big companies are required to know how to use computer to manage the project or only composing the contract, saving the database, even making important data security for firm. In fact, A great benefit that a computer certainly works effectively and has replaced thousands of people to solve complex tasks by only one person or group. That saves much money and time and even worker's strength. And the computer is an intelligent device for students to study, especially IT students. They can search for documents that are related to their curriculum or any information they are interested in their life on the internet if that computer has a global network. On the other hand, most of the people are tired after sitting with computers for work a long time in the day, may relax their mind with many kinds of games they want, listen to music, study English and so on...In a word, the computer is the best device for everyone for many various purposes. However, some people use computer for a bad idea. it is nothing to use for children are crazy about games day by day. That makes children don't continue to study and their marks are gradually lower and lower. Furthermore, it is easy to attract crazy children and students with a depraved culture. In my opinion, our government is forbidding strictly behaviors uploading badly depraved things on the internet. And certainly have to advice children and their parents to avoid putting bad those on their computer. I strongly disagree with people who make children go down in our developing country who will be the main leader of our country in the future. Thanks for your reading and be glad to see your writing on this topic.Thanks...thanks.

Computer plays an important role in this technology era. It can't be denied that computer brings certain advantages, but this high-tech device has its own limitations.

First of all, computer has become a useful tool and an intelligent device in every aspect of life. For example, thanks to Computer and Internet, studying has no hurdles, because Internet is an unlimited source of information and knowledge. What is more, computer and Internet is a great means of communication. Distance is no longer a matter of concern when we can send mails within a few seconds or make cheap internet phone call. We can use computer whenever and wherever we can. That is to say computer has made our life become modern, more convenient and civilized.

However, it has its own disadvantages. The troubles, however, do not stem from computer or the Internet themselves but the users. The new technology is entirely positive but the users take its advantage for negative purposes. Some people use computers to do nothing but play games, chitchat, spam, create dirty information on the Net. They directly or indirectly detract Internet from its benefits to the community. Many people are scared of using Internet because of their fear of being abused, or spamed, or becoming Internet addicts. In addition, sitting in front of the screen for long hours can lead to obesity, backache, and short-sightedness. Besides, people paying too much attention to online activities may become passive, sluggish in real life because of their lacks of communication, and manual labor.

In short, everything has its two sides, so does computer and Internet. Therefore, it is necessary that we use it for right purposes.
