USES OF COMPUTERS

Education :
Getting the right kind of information is a
major challenge as is getting information
to make sense. College students spend an
average of 5-6 hours a week on the
internet.Research shows that computers
can significantly enhance performance in
learning. Students exposed to the internet
say they think the web has helped them
improve the quality of their academic
research and of their written work. One
revolution in education is the advent of
distance learning. This offers a variety of
internet and video-based online courses.
Health and Medicine :
Computer technology is radically changing
the tools of medicine. All medical
information can now be digitized. Software
is now able to computer the risk of a
disease. Mental health researchers are
using computers to screen troubled
teenagers in need of psychotherapy. A
patient paralyzed by a stroke has received
an implant that allows communication
between his brain and a computer; as a
result, he can move a cursor across a
screen by brainpower and convey simple
messages.
Science :
Scientists have long been users of it. A
new adventure among scientists is the idea
of a “collaboratory”, an internet based
collaborative laboratory, in which
researchers all over the world can work
easily together even at a distance. An
example is space physics where space
physicists are allowed to band together to
measure the earth’s ionosphere from
instruments on four parts of the world.
Business :
Business clearly see the interest as a way
to enhance productivity and
competitiveness. Some areas of business
that are undergoing rapid changes are
sales and marketing, retailing, banking,
stock trading, etc. Sales representatives not
only need to be better educated and more
knowledgeable about their customer’s
businesses, but also must be comfortable
with computer technology. The internet
has become a popular marketing tool. The
world of cybercash has come to banking –
not only smart cards but internet banking,
electronic deposit, bill paying, online stock
and bond trading, etc.
Recreation and Entertainment:
Our entertainment and pleasure-time have
also been affected by computerization. For
example:
i) In movies, computer generated graphics
give freedom to designers so that special
effects and even imaginary characters can
play a part in making movies, videos, and
commercials.
ii) In sports, computers compile statistics,
sell tickets, create training programs and
diets for athletes, and suggest game plan
strategies based on the competitor’s past
performance.
iii) In restaurants, almost every one has
eaten food where the clerk enters an order
by indicating choices on a rather unusual
looking cash register ; the device directly
enters the actual data into a computer,
and calculates the cost and then prints a
receipt.
Government:
Various departments of the Government
use computer for their planning, control
and law enforcement activities. To name a
few – Traffic, Tourism, Information &
Broadcasting, Education, Aviation and
many others.
Defence:
There are many uses computers in Defence
such as:
1) Controlling UAV or unmanned air-crafts
an example is Predator. If you have cable I
would recommend watching the shows
“Future Weapons" and “Modern Marvels".
The show future weapon gives an entire
hour to the predator.
2) They are also used on Intercontinental
Ballistic Missiles (ICBMs) that uses GPS and
Computers to help the missile get to the
target.
3) Computers are used to track incoming
missiles and help slew weapons systems
onto the incoming target to destroy them.
4) Computers are used in helping the
military find out where all their assets are
(Situational Awareness) and in
Communications/Battle Management
Systems.
5) Computers are used in the logistic and
ordering functions of getting equipments to
and around the battlefield.
6) Computers are used in tanks and planes
and ships to target enemy forces, help run
the platform and more recently to help
diagnose any problems with the platforms.
7) Computers help design and test new
systems.
Sports:
In today's technologically growing society,
computers are being used in nearly every
activity.
Recording Information
Official statistics keepers and some scouts
use computers to record statistics, take
notes and chat online while attending and
working at a sports event.
Analyzing Movements
The best athletes pay close attention to
detail. Computers can slow recorded video
and allow people to study their specific
movements to try to improve their
tendencies and repair poor habits.
Writers
Many sportswriters attend several sporting
events a week, and they take their
computers with them to write during the
game or shortly after while their thoughts
are fresh in their mind.
Scoreboard
While some scoreboards are manually
updated, most professional sports venues
have very modern scoreboards that are
programmed to update statistics and
information immediately after the
information is entered into the computer.
Safety
Computers have aided in the design of
safety equipment in sports such as football
helmets to shoes to mouth guards
