technology
Nearly
everything we do in the world is helped, or even controlled by computers.
Computers are used more and more often in the world today because they are far
more efficient than human beings. They have much better memory and can store a
huge amount of information.
Just as
television has extended human sight across the barriers of time and distance,
so the computers extend the power of the human mind across the existing
barriers.
Ordinary
computer can remember only the data stored in hard disk. Now scientists have
designed machines which are capable to learn from experience and remember what
they have learnt. Such a machine is capable to recognize objects without human
help or control.
The Internet
is a global collection of different type computer networks that are linked
together. Some refer to the Internet as the information superhighway. The
Internet enables a person to exchange information with other computer users
from anyplace of the world. The final destin
or countries.
It also offers
a rapidly growing collection of information, with topics ranging from medicine
to science and technology. It features exhaustive material about arts as well
as research material for students and coverage of recreation, entertainment,
sports, shopping, and employment opportunities. The Internet provides access to
almanacs, dictionaries, encyclopedias, and maps.
A common
resource provided by the Internet is a worldwide system for sending and
receiving electronic mail, known as E-mail. Unlike the regular mail, E-mail
often reaches its destination, even on other continents, in minutes or less.
There are,
however, some disturbing aspects to consider. Study of the social and
psychological effects of Internet showed that Internet-addicted people
experience higher levels of depression and lowliness than those people who use
the computer network less frequently. Researchers found that using of computer
and Internet causes a decline in psychological well-being.
