I am a computer, born in America in 1946. From then on I am growing smaller and smaller. Looking at my appearance, you will find I am made up of the following parts: the screen like my eyes, the keyboard like my legs and the mouse like my hands. With time going by, the Internet arose. More functions have been added to me. Now I am good at dealing with a wide range of information, such as news from all fields sports entertainment and weather forecast and so on. With the help of the Internet, just a click, human beings will be well-informed of what is happening around the world every day. As a result I am a perfect assistant of human race in a way. I am so well equipped now that I hope I can be accessible to more people and serve people as a devoted friend.
