Computer (Microprocessor) Applications

The application of microprocessors is increasing day by day. There are numerous applications of microprocessors. They are used in industry, instrumentation, transportation, military equipments like Tank, Radar etc.; banks, business organizations, communication, automatic testing of products, lift control, speed control of motors, automatic control of generator’s voltage, consumer and commercial applications etc. now smaller institutions, business organizations, small industries etc. can afford to have a microcomputers for general purpose computation or dedicated application. Microcomputers are also used to store and display information.

The original objective for the inventions of a digital computer was to create a fast computing machine. But today a large percentage of the applications of digital computers are of non-mathematical or non numerical nature. They are used for storing, displaying and transmitting information. As a computer is a very fast machine, information are transmitted at very high rate. This feature attracts people to use digital computers for bulk storage and easy display of information.

A few examples of computer applications have been given below

WORD PROCESSING: Now day’s Computers are widely used in offices for preparations of texts, their storage and retrieval when required. Such work is known as word processing. Word processing of words allows us to create, view, edit, store, retrieve and print text. A word processing software which performs the task of word processing. A word processing system is highly automated electronic typing machine. As the text is entered with the keyboard, it is displayed on the CRT screen. The user is able to views what he was typed. He can make corrections, add works of sentences and delete works or sentences. He can specify left and right margins, spacing, number of lines per page etc.

RESERVATION FOR AIRLINES AND RAILWAYS: For reservations microcomputers have been introduced. These microcomputers are connected to supercomputer via satellite. The officer incharge can get information from other cities of world regarding the availability of seats in a plane for particular date. They also get information’s about hotels, climates etc.

INDUSTRIAL AND COMMERCIAL APPLICATIONS: The microprocessor based systems have numerous applications in industries. Take the example of power plant control. A microprocessors based system indicates the voltage, power, power factor, current frequency etc. of each generator on CRT.

GENERAL APPLICATIONS: a microprocessor based system can also used to control the efficient burning fuel in a car. It can be used for traffic light control, lift control, robotics etc. Robots have mechanical hands and legs and optical sensors to the obstacles. They are controlled by microcomputers. They perform tasks according to the program fed to them.

DATA ANALYSIS: Computers are extensively used for data analysis. Special program known as spreadsheet program is available for such work. When data are entered in rows and columns on a sheet of paper it is called as spreadsheet. The spreadsheet prepared in computer is called as electronic spreadsheet. Spreadsheet programs are used in accounting work, sales analysis, inventory control, tabulation of marks, and number of business and non business data analysis works.

COMPUTER GRAPHICS: Computers are powerful tool to prepare drawings, pictures, graphs and charts. Graphics software packages are available for such work. Complex engineering drawing in multicolour are now easily designed and produced with the help of computers. A computer can produce three dimensional drawing and pictures. Pictures can be rotated, reduced or enlarged.

DATABASE MANAGEMENT: A database is collection of related files. A file is the collection of record. Database management programs are available to create and handle database. Take an example of database to keep the personal files of employees of an organization. The stored information include name, identification number, age, qualification, experience, specialization, the section in which the employee is posted etc. from this database if the identification number of an employee is given, all information about that employee is immediately available.

BANK: computers are extensively used by bank for general purpose computations, to entertain customers at the bank counters, to allow customers to make transaction from remote terminals and to process cheques and drafts which are received in large volume in bank everyday. At bank counter a customers can make withdrawals and deposits himself using computer. With the introduction of computer electronic transfer of funds from one account to another has become possible. A customer from bank counter, home, office or hotel can make transaction using computer.

OTHER APPLICATIONS: nowadays computers are being used in stores, shops, hotels, schools, colleges, hospitals, video games, and so on and so forth. They are used in smart camera, in smart taximeter, photograph processing laboratory, to transmit messages from one place to another, video conferencing, computer information system, online investment brokerage system, communication including satellite communication, education, research, library, artificial intelligence, smart crane, smart watch, smart phone and so on.
