Some of the major application areas include:
1. Scientific, Engineering and Research:
This is the major area where computers find vast applications. They are used in areas which require lot of experiments, mathematical calculations, weather forecasting, and complex mathematical and engineering applications. Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) help in designing robotics, automobile manufacturing, automatic process control devices etc.
2. Business:
Record keeping, budgets, reports, inventory, payroll, invoicing, accounts are all the areas of business and industry where computers are used to a great extent. Database management is one of the major area where computers are used on a large scale. The areas of application here include banking, airline reservations, etc. where large amounts of data need to be updated, edited, sorted, searched from large databases.
3. Medicine:
Computerized systems are now in widespread use in monitoring patient data like , pulse rate, blood pressure etc. resulting in faster and accurate diagnosis. Modern day medical equipment are highly computerized today. Computers are also widely used in medical research.
4. Information:
This isthe age of information. Television, Satellite communication, Internet, networks are all based on computers.
5. Education:
The use of computers in education is increasing day by day. The students develop the habit of thinking more logically and are able to formulate problem solving techniques. CDs on a variety of subjects are available to impart education. On line training programs for students are also becoming popular day by day. All the major encyclopedias, dictionaries and books are now available in the digital form and therefore are easily accessible to the student of today. Creativity in drawing, painting, designing, decoration, music etc. can be well developed with computers.
6. Games and Entertainment:
Computer games are popular with children and adults alike. Computers are nowadays also used in entertainment areas like movies, sports, advertising etc.
7. Defence:
There are many uses computers in Defence such as:
- 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.
- They are also used on Intercontinental Ballistic Missiles (ICBMs) that uses GPS and Computers to help the missile get to the target.
- Computers are used to track incoming missiles and help slew weapons systems onto the incoming target to destroy them.
- Computers are used in helping the military find out where all their assets are (Situational Awareness) and in Communications/Battle Management Systems.
- Computers are used in the logistic and ordering functions of getting equipments to and around the battlefield.
- 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.
- Computers help design and test new systems.
