Now, there are lots of teenagers use computer to study and relax. It's very convenient. Benefits of computers include efficient operations in business and enhanced learning capabilities. Computers also bring cultures and families together by allowing people to communicate directly through the Internet with online chat and email. But, using computer is not good at all. Children who spend hour after hour on the computer may be damaging a vital part of their brains. They play computer games instead of out door activities. It's so harm. People should only use computer 1 hour a day.

Computer is a modern tool which has made life very easy and simple. It has the capability to complete more than one task in small time. It is able to do work of many human beings alone within less time. It is the utility of highest efficiency. The first computer was a mechanical computer which was created by the Charles Babbage. A computer works successfully using its hardware and fully installed application software. Other accessories of the computer are keyboard, mouse, printer, CPU and UPS.
The data which we put into the computer using device is called input data and device as input device and data which we take outside using printer or the other device is called as output data and device as output device. The input data gets changed into the information which can be stored and changed anytime. Computer is very safe tool for data storage which is being used in various fields. We can shop, pay our electricity bill, water bill, video chat, messaging, e-mail messages anywhere in the world and lots of online activities using the internet.
Beside a lot of advantages, computer has some disadvantages too. First of disadvantages is that people who spend too much time sitting in the front of computer can easily gets ill. Radiation emitted by computer’s screen is harmful to eyes. People who spend too much time at their homes (because they needn’t go anywhere, they can do everything using Internet) are getting weaker. Sitting a for long time is also harmful to the spine.
Second disadvantage is that Internet ( program in computer ) can by addictive. Some people just can’t live without it. They have no real friends and when Internet is down they are getting furious.
Internet has some opponents but more and more people treats Internet like telephone, or radio. They use it for fun and work, and I think at present living without internet would be quite difficult.
In short, computers have many benefits and disadvantages. We should use it more balanced!
