Characteristics of computers- Features of Computers

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.

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.

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.

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.
