Storage, processing and dissemination of information play a very important role in modern information society. Computers, telecommunications, data and computuer communications contribute tremendously to these activities. Computers and electronic communications are getting closer and closer every day. Computers, electronic communications and other technologies associated with automation come under the general term of information technology. Information technology influences our lives and its impact on society is increasing day by day.
A computer can perform calculations at a speed beyond human ability and with accuracy and consistency which people can not match. Some of the knowledge we process today would be unknown without the east computational power of computers. The rapid social, economic, cultural and technological changes cannot be imagined without the east computational speed of present day computers.
Present world is so much dependent is so much dependent on computers that If they could be taken away overnight, the airlines, electronic communications, financial operations and official activities would collapse. There are many more examples like these. It is not possible for an average person to appreciate the direct and indirect impact of computers in society. Computers have penetrated human society far more deeply than average persons can really appreciate.
The following are some important criteria, which may be used to justify the use of computers:
Volume of data :
The computer is suited to handling large unutod of data.
Accuracy :
Computers ensure high degree of accuracy and their consistency is reliable.
Repetiveness :
Processing cycles that repeat time and time again are ideally suited to computers. Once a computer is programmed. It goes on automatically performing the task as many times as required.
Complexity :
Computers perform complex calculations. A computer provides the required answers after running the program for complex calculations.
Speed :
Computers work at very high prefer and this enables them to respond quickly to a given situation.
Common data:
One item of data can be used for different computer procedures. A combination of two or more of the above criteria usually justifies the use of computers. These criteria are used to carry out the preliminary survey to lugge the suitability of applications for computerization. Technological innovations in the recent part have increased the range of technically feasible applications and they also provide cost effective solutions to a range of problems. If the general criteria justify that a particular application may be suitable for computerization, then the following questions should be satisfactorily answered before taking any decision for computerization.
1) Is the use of a computestfbimically feasible ?
2) Would it be cost effective ?
3) Would it be socially caestable ?
Besides the advantages of using a computer, there are a few limitations of it. There are
1) Computers can not think
2) Computers can not do anything without human instructions.
3) Computers can not make any adjustment as human being can do .
Okay bye now. I think its very usefull artical for you.
