Computer technology has become a major part of people's lives. This technology has its own special words. One example is the word " mouse". A computer mouse is not a small animal that lives in buildings and open fields. It is a small device (装置) that you move around on a flat surface in front of a computer.The mouse moves the cursor (光标) on the computer screen.
Computer expert Douglas Engelbart developed the idea for the mouse in the early nineteen-sixties. The first computer mouse was a carved block of wood with two metal wheels. It was called a mouse because it had a tail at one end. The tail was the wire that connected it to the computer.
Using a computer takes some training. People who are experts are sometimes called hackers. A hacker is usually a person who writes software programs in a special computer language. But the word" hacker" is also used to describe a person who tries to steal information from computer systems.
Another well known computer word is Google. It is the name of a popular search engine for the Internet.People use the search engine to find information about almost any subject on the Internet. The people whostarted the company named it Google because in mathematics, googol, spelled g-o-o-g-o-l,is an extremely
large number. It is the number one followed by one hundred zeros.
When you "Google" a subject, you can get a large amount of information about it. Some people like to Google their friends or themselves to see how many times their name appears on the Internet. If you Google someone, you might find that persons name on a blog. A blog is the shortened name for a Web log. A blog is a personal Web page. It may contain stories, comments, pictures and links to other websites. Some people add information to their blogs every day. People who have blogs are called bloggers.
