WHY WE NEED COMPUTER
A computer has six chief features, which are as
(1) Speed (2) Accuracy (3) Storage
(4) Tirelessness (5) Automation (6) Versatility
SPEED
A computer is an electronic device in which electrical signals travel at the speed of light. So, a computer does its jobs very speedily. It never slows down. Continue keep working at a uniform speed. Computer can be execution of a command in Nino sec.
ACCURACY
A computer is never makes error normally. But errors may occur in its hardware. No error 100% accuracy.
STORAGE
A computer system unit is capable of storing a large amount of data in its memory. Not only this, it can produce the data again and again on demand. A human brain cannot do that.
TIRELESSNESS
Unlike human beings and other animals, a computer never gets tired or bored if it has to do the same job again and again. Even if it has to do million calculations, it will do the last on with the same speed and accuracy as the first one.
AUTOMATION
Once the instructions have been given a computer can carry on its job automatically till it is complete.
VERSATILITY
A computer is capable of performing a large number of different jobs working logically step by step.
