Application of computers

Practically, every company, large(or) small, is now directly(or) indirectly dependent on computers for information processing. Computer systems also help in the efficient operations of railway and airway reservation hospital records, accounts, electronic banking, and so on. Computers not only save time but also save paperwork. Some of the areas where computers are being used are listed below.

Science

The scientist has been using computers to develop theories to analyze and test data. The fast 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 patterns. Satellite-based applications have not been possible without the use of computers. It would also not be possible to get information about our solar system and the cosmos without a computer.

Education

The computer has also revolutionized the whole process of education. Currently, classrooms, libraries, and museums are utilizing computers to make education much more interesting. Unlike recorded television shows, Computer-Aided Education(CAE) and Computer Based Training(CBT) packages are making learning much more interactive.

Medicine and Healthcare

There has been 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 imagining techniques, doctors are able to look inside a person’s body and can study each organ in detail which was not possible a few years ago. There are several examples of special-purpose computers that can operate within the human body such as a cochlear implant, a special kind of hearing aid that makes it possible for deaf people to hear.

Engineering / Architecture / Manufacturing

Architects and engineers are extensively using computers in designing and drawing. Computers can create objects that can be viewed from all three dimensions. By using techniques like virtual reality, architects can explore however that have been designed but not built. Besides, Computer-Aided Manufacturing(CAM) can be used in designing the product, ordering the ports, and planning production. Thus, computers help in co-coordinating the entire manufacturing process.

Entertainment

Computers are finding greater use in the entertainment industry. Computers are used to control images and sounds. The special effects, which mesmerize the audience, would not have been possible without the computers. In addition, computerized animation and colorful graphics have modernized the film industry.

Communication

E-mail (or) electronic mail is one of the communication media in which a computer is used. Through e-mail, messages and reports are passed from one person to one or more persons with the aid of a 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. Moreover, the person who is receiving the messages can read the messages whenever he is free and can save them, reply to them, forward them (or) delete them from the computer.

Business Application

This is one of the important uses of computers, initially, computers were used for batch processing jobs, where one does not require an immediate response from the computer. Currently, computers are mainly used for real-time applications (like at the sales counter). That requires an immediate response from the computer.

There are various concerns for which computers are used such as in business forecasting, to prepare pay bills and personal records, in banking operations and data storage in the 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 data and information. use of e-mail and the internet has changed the ways of business.

Publishing

Computers have created a field known as DTP(Desktop Publishing). In DTP, with the help of a computer and a laser printer, one can perform the publishing job all by oneself. Many of the tasks requiring long manual hours such as making a table of contents and index can be automatically done by the application of computers.

Banking

In the field of banking and finance, computers are extensively used. People can use the ATM(Automated Teller Machine) services 24 hours of the day in order to deposit and withdraw each. When the different branches of the bank are connected through the computer networks then the inter-branch transaction such as cheque and draft can be done by the computers without any delay.
