Applications of Computers

Word processing : 

Word processing software enables users to read and write documents. Users can also add images, tables, and graphs for illustrating a concept. The software automatically corrects spelling mistakes and includes copy-pastes features.

Internet : 

The internet is a network of networks that connects computers all over the world. It gives the user access to an enormous amount of information. Using e-mail, the user can communicate in seconds with a person who is located thousands of miles away. Chat software enables users to chat with another person in real-time. Video-conferencing tools are becoming popular for conducting meetings with people who are unable to be present at a particular place.

Digital video or audio composition :

Computers make audio or video composition and editing very simple. Graphics engineers use computers for developing short or full-length films and creating 3D models and special effects in science fiction and action movies.

Desktop publishing : 

Desktop publishing software enables you to create page layouts for entire books. Different areas where computers are being widely utilized.

Government:

Computers are used in government organizations to keep records on legislative actions, internal Revenues Service record, etc.

Traffic Control:

In the United States, computers are used by the government for city planning and traffic control.

Legal System:

Computers are used by lawyers to shorten the time required to conduct legal precedent and case research. Lawyers use computers to look through millions of individual cases. Moreover, computers are also used to keep track of appointments and prepare legal documents and briefs in time for filling cases.

Retail Business:

Computers are used in retail shops to enter orders, calculate costs, and print receipts. They are also used to keep an inventory of the products available and their complete description.

Sports:

In sports, computers are used to compile statistics,  identify weak players and strong players by analyzing statistics, sell tickets, create training programmes and suggest game plan strategies based on the competitor’s past performance.
Television networks use computers in the control room to display action replays and insert commercial breaks as per schedule.

Music:

All computers today have musical instrument digital interface (MIDI) facility, which links musical instruments to a PC, thereby enabling the computer to generate a variety of sounds.  Moreover, the background music in movies, TV shows, and commercials are all generated electronically using computers.

Movies:

Computers are used to create sets, special effects, animations, cartoons, imaginary characters, videos, and commercials.

Travel and Tourism:

Computers are used to prepare tickets, monitor the routes of trains and aeroplanes, and guide planes to a safe landing. They are also used research about hotels in an area, reserve rooms, or to rent a car.

Business and Industry:

In business and industry, computers are used mainly for data processing, which includes tasks such as word processing, analyzing data, entering records, payroll processing, personnel record keeping, and inventory management.

Hospitals:

Hospitals use computers to record every information about patients from the time of their admission till their exist. Moreover, computer-controlled devices are widely used to monitor pulse rate, blood pressure.

Simulation:

Supercomputers that can process enormous amount of data are widely used in simulation tests. Simulation of automobile crashes or aeroplane emergency landings is done to identify potential weakness in designs without risking human lives.

Geology:

Civil engineers use computers to evaluate the effects of an earthquake on the structure of buildings based on age, proximity to the fault, soil type, size, shape and construction material.

Astronomy:

Spacecrafts are usually monitored using computers that not only keep a continuous record of the voyage and of the speed, direction, fuel, and temperature, but also suggest corrective action if the vehicle makes a mistake.

Weather Forecasting:

When computers are fed with mathematical equations along with data about air pressure, temperature, humidity, and other values, the solution of these equations gives an accurate prediction of the weather of a particular area.

Education:

A computer is a powerful teaching aid and acts as another teacher in the classroom. Teachers use computers to develop instructional material. Teachers may use pictures, graphs, and graphical presentations to easily illustrate an otherwise difficult concept. Most students also prefer to learn from an e-learning software rather than from a book. Students can also give online exams and get instant results.

Online Banking:

The world today is moving towards a cashless society, where you need not have money in your pocket to purchase anything. You can just have your credit card or debit card with you. The ATMs provide a 24 ´ 7 service and allow you to draw cash, check the balance in your account, and order a product.

Industry and Engineering:

Computers are found in all kinds of industries, such as thermal power plants, oil refineries, and chemical industries, for process control, computer aided designing (CAD), and computer aided manufacturing (CAM).

Computerized process control (with or without human intervention) is used to enhance efficiency in applications such as production of various chemical products, oil refining paper manufacture, and rolling and cutting steel to customer requirements.

Robots:

Robots are computer-controlled machines mainly used in the manufacturing process in extreme conditions where humans cannot work, for example, in high-temperature, high-pressure conditions or in processes that demand very high levels of accuracy.

Decision Support Systems:

Computers help managers to analyse their organization’s data to understand the present scenario of their business, view the trends in the market, and predict the future of their products. Managers also use decision support systems to analyse market research data, to size up the competition, and to plan effective strategies for penetrating their markets.

Expert Systems:

Expert systems are used to automate the decision-making process in a specific area, such as analyzing the credit histories for loan approval and diagnosing a patient’s condition for prescribing an appropriate treatment. Expert systems analyse the available data in depth to recommend a course of action. Computers are used to find jobs on the Internet, find a suitable match for a boy or girl, read news and articles online, find your batch mates, send and receive greetings pertaining to different occasions, etc.
