Computer technology has become an important part of people's life. This technology has its own special
words. One well-known computer word is Google. It's the name of a popular "search engine (引擎)" for
the Internet. People use the search engine to find information about almost any subject on the Internet.
The people who started the company named it Google because in math Google is a very large number-One
hundred zeros follow the number one. When you "Google" a subject, you can get a lot of information about
it.
If you Google someone, you might find that person's name on a blog (博客). A blog is short for a Web
log. It's a personal Web page. Some people write blogs to express their opinions and ideas over the Internet.

blogs every day. People who have blogs are called bloggers.
