- Produce monthly bill statements, salary sheets and mark sheets.

Using multimedia system teachers can present lessons in more understandable and in an organized way. Students also can learn subjects themselves using computers. They can browse internet to get information related to their lessons.

2. In Designing and Engineering: Computers are used for designing clothes, magazines, book covers etc. Engineers use computers to help them create designs of new houses, buildings, bridges, machines, cycles, vehicle etc.

3. In Entertainment: Computers are used to create characters and various animations. They are also used for playing various computer games at home. Computers can be used to watch T.V programs and movies. Audio music can also be played in the computer. In a movie special effects are put with the help of computers to make the movie more realistic and more interesting. Film producers take the help of computers to make cartoon movies and animation films. Music composers use computers for composing music and to set various notes and tunes accurately. In radio stations and FM stations, computers are used to manage and play songs, advertisement etc. Computers are used for creating new notes and rhythm (timing) in music. Musicians use computers to compose and develop music in a much quicker and faster way.

4. In Medical fields: Scientists and doctors take the help of computer in the research and development of new medicines to fight new diseases. In hospitals, computers are used to keep records of patients’ diseases, different medical tests and treatment of diseases. For the diagnosis of diseases, doctors take help of special computer (ECG machine, Ultrasound Machine, CT-Scan machine and others machines). In Intensive Care Unit (ICU) of hospitals, special computers are used to monitor the condition of patients and record the necessary information. Computers are used in hospitals and clinics for carrying out different medical tests. Doctors use computers to keep records of patients for future use. Computers are used to examine the progress of a patient under intensive care.

5. Printing and Publishing: Computers are used for publishing and printing books in various shapes and sizes. Computers help in providing error-free documents for newspapers on time.

6. In Science and Technology: Computers are used in the invention and development of different modern scientific instruments and equipments. Space satellites are linked with computers to control and monitor the proper functioning of aeroplanes and space equipments. Scientists use computers in different experiments. They use computers in scientific research works and in space research.

7. Transport: Computers are used for seat reservations, control and maintaining timetables of vehicles etc. One can reserve his/her seat from the hotel itself and get it confirmed without having to go to the station or the airport.

8. In Banking field: Computers are used in banks to handle thousands of accounts and calculations of payments receipts, cheques etc. Accounts can be transferred from one place to another from one’s home itself.

9. Defense: Computers are used in defense services for monitoring secrets of enemies and different other satellite technology. Computers are also used in the invention and development of new weapons for defense uses. Computers are also used in keeping track of weapons and ammunitions produced and used.

10. In Offices: Computers are used in offices to prepare different kinds of documents. Computers help in keeping records of office employees. Computers also help in sending Electronic mails (email).

11. In Factories: In the big factories computers are used to control machines and tools. Computers are used to control the quality of products. In the factories like car manufacturing factories, aircraft manufacturing factories, microprocessors manufacturing factories and many others factories computer controlled machine ‘ROBOTS’ are used to handle those jobs where it is risky, very sharp accuracy is needed or heavy equipment are to be joined.

12. In Electric Appliances: In homes, tiny computers embedded in the electronic circuitry of most appliances control the indoor temperature, operate home security systems, tell the time, and turn videocassette recorders (VCRs) on and off. Computers in automobiles regulate the flow of fuel, thereby increasing gas mileage, and are used in anti-theft systems.
