Impact of Computers

Commerce, industry, education, administration, transportation, communication etc and many other organizations, professions and individuals depend on computers and their applications directly or indirectly. Impact of computers on few important areas of human activities is discussed briefly.

Commerce :

Banking, insurance, credit companies, airlines, shopping centers and many business concerns need computers  for their daily operations. They form the majority users of computers. Financial world connot survive without assistance from computers. Commerce offer quick communication and businesses depend much on computer communications, computer bulletin boards, e-mail, e-commerce and the internet. Impact of such items can only increase in the future. Financial success of a nation cannot be imagined without the successful use of computers in business activities.

Industry :

Many industries such as the steel, chemical and oil companies rely on computers for the actual control of plant processes. This trend can only increase, in the future. Microprocessors  are used in harsh environments : in extreme cold and in dirty and noisy atmosphere. Many of the tasks involved in assembly work as in the motor-car, washing machine and television industries are undertaken by processes controlled by Microcomputers

Many sophisticated industrial control and manufacturing processes cannot be imagined without microcomputer boards, embedded microprocessors and robots. Computer aided designing (CAD), computer aided manufacturing (CAM) and computer aided design manufacture and testing (CADMAT) are popular for many industries.

Education :

In future much of the traditional teaching will be performed with the help of computers. This form of teching is known as computer-assisted instruction (CAI) and computer-assisted learning (CAL). Technically this is possible and indeed exists in some countries. In the institutions of higher education  the computer ghas become an indispensable tool for undergraduates and postgraduates for arts, science, business, technology etc. Many of the current projects undertaken by postgraduates would be impractical without computers.

Interactive multimedia, electronic libraries and the information superhighway play a major role in providing a range of interactive courses and services. Thus the educational institutions are termed as virtual learning environment, besides a physical campus. Such institutions are termed as virtual institutions of learning.

Administration :

Many of the administrative tasks are profaned by computers. Word-processing, spreadsheet analysis, database management, pay roll, automatic order processing are some examples. Interpersonal and inter-office messaging, which is popularly known as electronic mail, is essential for quick and effective way of communication for administration. Videoconferencing is a common place for official and administrative activities in some nations. Automatic offices of the future will be dependent on computers, electronic communications and computer networking.

Transportation :

Sea and air transportations of today relay on computers and computer communications. Many road transport companies in advanced countries use cellular and satellite communications to prepare optimized routes for the vehicles and for sending instructions to the drivers and operators. Computer controlled traffic systems provide efficient management of traffic in some major cities of the world.

Networks and Communication :

Information networks provide services to end users through communication links between microcomputers. The major components of computer networks are the centrla computer, database, the communication links and microcomputers. The future telephone will be incorporated into the microcomputer and one will not only hear but also see the person on other done of the line. The users will be able to pass data and information back and forth as if they were sitting at the same table.

Other Professions :
Law, medicine, libraries, armed forces and many other professions and working environments make use of computers and therefore depedne upon computers. This emphasizes computer literacy and computer education in the society.

Individuals :

 Even if we are not directly concerned with computing in our everyday work, as individuals we are affected by them in one way or other. Air passengers, hospital patients, the shoppers in large store are some of the people for whom computers process information. Tax, electricity, telephone or gas bills are processed by computers and salaries are calculated by computers, indeed, it is difficult to find anyone who in some way or another does not depend on computers.
