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.
