The increasing popularity of computers has proved that it is a very powerful and useful tool. The power and usefulness this popular tool is mainly due to its following characteristics:
1.Automatic:A machine is said to be automatic, if it works by itself without itself without human interventions. Computer is automatic machines because once on a job, they carry on, until the job is finished, normally without any human assistance. However, computers being machines cannot start themselves. They cannot go out and find their own problems and solutions. They have to be instructed. That is, a computer works from a program of coded instructions, which specify exactly how a particular job is to be done. Some of the other characteristic of computers, such as speed and accuracy, are due to the fact they are automatic, and work on a problem without any human intervention.
2.Speed:A computer is very fast device. It can perform in a few seconds, the amount of work that a human being can do in an entire year- if he worked day and night and did nothing else. To put it in a deference manner, a computer does in one minute what would take a man his entire lifeline.
3.Accuracy:In additions to being very fast, computers are very accurate. The accuracy of computer is consistent high, and the degree of accuracy of particular computer depends upon its design. However, these are mainly due to performed with the same accuracy.
4.Diligence:Unlike human beings, a computer is free from monotony, trendless and lack of concentration. It can continuously work for hours, without creating much error and without grumbling, hence, computers score over human beings in doing routine type of jobs, which require great accuracy. If ten million calculations have to be performed, a computer will perform the ten millionth calculations with exactly the same accuracy and speed as the first one.
5.Versatility:Versatility is one of the most wonderful things about the computer. Once moment, it is preparing the results of examinations, the net moment, it is busy preparing electronic bills, and between, it may be helping an offices secretary to trace a important letter in seconds. All that is required to change its talent is to slip in a new program into it. Briefly a computer is capable of performing almost many tasks, if the task can be reduced to a series of logical steps.
6.Power of Remembering: As a human being acquires new knowledge, the brain subconsciously selects what it feels to be important and worth retaining in memory, and relegates unimportant details what it feels. This is not case with computers. A computer can store and recall any amount of information because of its secondary storage (a type of detachable memory) capability. Every piece of information can be retained as long as desired by the user, and can be can be recalled. As and when it was fed to the computer several years, the information recalled would be as accurate as on the day when it was fed to the computer. A computer. A computer forgets or looses certain information only when it is asked to do so. Hence, it is entirely up to the user, to make a computer retain or forget particular information.
7.No Feelings:Computers are devoid of emotions. They have no feelings and no instincts because they are machines. Although men have succeeded in building a memory for the computer, but no computer possesses the equivalent of a human heart and soul. Based on your on our day-to-day life. However, computer to then in the form of programs that are written by us.
