Education
computers have also revolutionized the whole process of education.
Currently, the classrooms, libraries and museums are efficiently utilizing computers to make
the education much more interesting.
Unlike recorded television shows, computer-aided education (CAE) and computer-based
training (CBT) packages are making learning much more interactive.
Science
Scientists have been using computers to develop theories and to analyze and test the data.
The high speed and accuracy of the computer allow different scientific analyses to be carried
out.
They can be used to generate detailed studies of how earthquakes affect buildings or pollution
affects weather pattern. Satellite-based applications have not been possible without the use
of computers.
Moreover, it would not be possible to get the information of the solar system without
computers.
Medicine and Health Care
There has been an increasing use of computers in the field of medicine.
Now, doctors are using computers right from diagnosing the illness to monitoring a patient's
status during complex surgery. By using automated imaging techniques.
Doctors are able to look inside a person's body and can study each organ in detail (e.g. CT
scans or MRI scans) which was not possible few years ago.
There are several examples of special-purpose computers that can operate within the human
body such as cochlear implant, a special kind of hearing aid that makes it possible for deaf
people to hear.
Engineering/Architecture/Manufacturing
The architects and engineers are extensively using computers in designing and drawings.
By using techniques like virtual reality, architects can explore houses that have been designed
but not built. The manufacturing factories are using computerized robotic arms to perform
hazardous jobs.
Computer-aided manufacturing (CAM) can be used in designing the product, ordering the
parts and planning production. Thus, computers help in coordinating the entire manufacturing
process
Entertainment
Computers are finding greater use in entertainment industry.
They are used to control the images and sounds. The special effects which mesmerize the
audience, would not have been possible without the computers.
Computerized animation and colorful graphics have modernized the film industry.
Communication
E-mail or electronic mail is one of the communication media in which computer is used.
Through e-mail, messages and reports are passed from one person to one or more persons
with the aid of computer and telephone line.
The advantage of this service is that while transferring the messages it saves time, avoids
wastage of paper and so on.
Business Application
This is one of the important uses of the computer.
Currently computers are mainly used for real-time applications (like at the sales counter) that
require immediate response from the computer.
There are various concerns where computers are used such as in business forecasting, to
prepare pay bills and personal records, in banking operations and data storage, in various
types of life insurance business and as an aid to management.
Businesses are also using the networking of computers, where a number of computers are
connected together to share the data and the information. Use of e-mail and the Internet has
changed the ways of doing business.
Banking
Computers are extensively used in the field of banking and finance.
People can use the ATM (automated teller machine) services 24 hours a day to deposit and
withdraw cash.
When different branches of the bank are connected through computer networks, the inter
branch transactions such as cheque and draft can be performed without any delay.
