Computer and their utilizes

Computer is a greatest invention which enables the human being to complete the tasks with the use of less time while eliminating repetitive activities. This it achieves by imitating human thought processes. Same way as human thinks the computer also has the ability to think in advance mode using electrical knowledge. This has electrical circuits as well. These are used because to increase the speed of processing.

In this contemporary era man has mature to be profoundly reliant on computers to carry out all kinds of jobs that were done by hand before. Some examples where computer is being used are as follows.

- In banking for example computers allow for millions of transactions to be carried out involving large sums of money which would otherwise require thousands of bank tellers.

- Computers do the job in a much shorter time and practically free of any errors. Computers are responsible for air traffic control and the running of trains to ensure that travel is made as smooth as possible.

- In factories nowadays computers operate mechanical devices that produce goods we require for everyday living, in such quantities that would be otherwise impossible to achieve if these factories were run by humans alone.

With the use of computers the most advanced field is in the communication and the most popular way of accessing a large amount of people is Internet. The internet is a collection of computer systems and individual terminals linked up worldwide through telephone lines and other channels. It offers a cheaper alternative to communicating with people within a country and internationally through computers. It has also been described as an enormous pool of knowledge just waiting for applications it has given rise to a new means for countries to carry on trade with each other through E-Commerce.

It must though be kept in mind that as useful as computers are. They are not capable of independent thought and still require human input. In recent times scientists have developed Artificial Intelligence in computers that may enable them to function independently of man in the future.
