Computer The Craze and the Need of the Age

English Essay on "Computer The Craze and the Need of the Age"

Commuter has brought about an amazing revolution in life around. Its use, now it so seems, has become a necessity, and has created for itself indispensability. Whether one goes to a railway station or to an airport for reservations or to the market for purchases or to any bank to withdraw money or to know the balanced of one’s account — on the table is the computer telling one in no time all the details one wants to know.

Does it not look wonderful that sitting in one city up north one can get his reservations in trains done or cancelled in deep South of one’s country thousands of miles away; or to perform the same feat in one’s air-travels from one country to another. Messages can be transmitted in the twinkling of an eye on E-mail or Fax. Letters which used to take days and even weeks sometimes are sent and delivered right here and now. Money can be withdrawn from one’s account by just pressing the button of the booth of our bank by the road side, sliding into it one’s account number card and crisp notes are available in another slot of the same machine, no hassles of presenting the cheque, asking for the balance or getting the payment — everything so automatic and so quick. In the busy world of today, going busier every day, such ready service is saving so much time, so much energy and so much manpower. In the medical science, particularly in the field of surgery, unthinkable and unimaginable feats are being performed — all with the help of computerised gadgets.

It should not, now be laughed at as a craze, It Is now the need of the age and now when we have entered the new century, we cannot Imagine what further wonders are In store for us. So what is this computer? This must be a natural inquisitiveness. A computer Is defined as an electronic device which has the ability to accept data and Instructions; store them, perform mathematical and logical operations and output the results. What is important ‘about computers is their characteristics which are — speed, storage, accuracy and versatility. Taking up these characteristics one by one, speed is to be found in the operations of computers which are caused by electrical pulses. As the electricity travels at the speed of light, a computer too can perform innumerable number of operations in just one second. This speed is measured in nanoseconds — one nanosecond is equal to billionth of a second.

So far the capacity of ‘storage’ is concerned, it has a very large storage capacity. The contents of around two hundred sheets of A4 size of paper can be stored on a small floppy disc which is not even half the size of one sheet of paper. As about the accuracy of computers — it should be said that computers do not make mistakes. Errors in computing are caused generally due to human negligence — feeding an inaccurate data, improper procedure, poor design etc., rather than technological faults.

Then comes the versatility of the computer. It can perform a wide range of jobs with speed and accuracy. In any organisation sometimes the same computer is used for diverse purposes such as preparing bills, generating pay slips, keeping track of the manager’s appointments and engagements; helping the secretaries in managing their correspondence etc.

There are several fields in which computer may be used or applied. The first such use is in business application. A business organisatlon — It may be public or private — a company, a government or a semi-government office — computers have been found as a very useful tool. They are used to take care of financial accounts, inventory control, stock control and similar other controls. The processing of financial accounts and transactions through computes have made the job faster and accurate.

The other use is in scientific applications. Science and research scholars are making use of computers for storing their information. Launching of a rocket or spaceship, whether forecasting, astronomical calculations etc. controlled through computers only. Their medical application has made the medical science most effective and life saving. Computers are used for planning and control purpose by health care professionals. They are used for treatment, planning and monitoring patients in the hospitals. Medical diagnosis has become easier and more accurate with the help of computers. For example — the symptoms detected by the physician could be fed into the computer and be compared with other symptoms and indications associated with the illness and probable diagnosis thus arrived at together with the prescriptions recommended earlier can be helpful in the process of treatment. For sophisticated operation like open heart surgery computerised machines are taken use of with successful results.

In the field of Engineering, computers are used as designing tool by architects and designers. CAD (Computer Aided Designing) is finding wide importance and acceptance in electronic, electrical and mechanical engineering. Apart from CAD, computers have moved into CAM (Computer Aided Manufacture) whereby they drive a set of CNC (Computerised Numeric Control) machines to manufacture various components without any human intervention.

Even our educational programmes are finding the use of computers very convenient and more effective. There are programmes written down to assist, students learn different subjects like Mathematics, Physics, Chemistry, Biology, Geography, Anthropology and such other subjects through computers. All these programmes form a part of Computer Aided Instruction (CAD) which helps students to execute the programmes as many times as they like at any place. Schools and educational institutions are using computers to keep students records for ready retrieval. Also, the examination results are processed on these machines. Computerised information collected and fed while investigating cases helps the law and order agencies. Libraries or museums have in the computers a ready reckoned of their data; of the number and nature of specimen or books available which otherwise would have meant a Herculean effort earlier.

Computers, as described above are playing a very important role’ in the everyday affairs and transactions of human life. What was once called the craze of modernity has become a dire need of the day without which no activity in any field seems possible.
