What do you feel about computer?
Everyone have their own feelings about it. Nowadays, we realize that computer can give a really big impact to all the users around the world. Everyone know how to use computer but they never know what computer really is and how do they work. For me, computer is a device which contain many programmes in it that can be used to complete any kind of tasks in our daily life. It is very useful to everyone especially among students. As we all know, it also has many advantages as well as disadvantages.
"Time is gold". Computer can help us to complete our tasks on time. By using a computer, anything can be done just in a second. That's means our life will become much easier. Moreover, from my perspective, computer is a interactive and sophisticated machine which allows different people to have access to same information and to communicate each other using e-mail. In order to communicate with someone using e-mail, we must send our message to their e-mail address.
Furthermore, by having a computer we can have our own space on the Internet. Internet can help us in order to know all the news or tragedies that already happened all around the world.
Because of that, we must use computer wisely and properly. Never misuse this sophisticated machine and the users must always be aware because computer also can lead us to the negative effects. Therefore, have fun using it in a proper way in order get a great impact to yourself and other people.
