CHARACTERISTICS OF A COMPUTER
Computer are very popular electronic machine .This popularity and importance of computer is due to following characteristics.
1)seed:- Computer perform oprations at a very high speed.It can solve complex calculations in a short time which may require years for a human.Toda,computer can execute millions of instructions per second.The time taken to perform a task by the computer is measured in fraction of seconds.The smaller units to represent these different franction of second are given in the table below:Unit of Time | Meaning | Part of Second | Power |
Millisecond(ms) | One thousandthe of a second | 1/1000 sec | 10-3sec |
Microseconds(us) | One millionth of a second | 1/1000000 sec | 10-6sec |
Nanoseconds(ns) | One billionth of a second | 1/1000000000 sec | 10-9sec |
Picosecond(ms) | One trillionth of a second | 1/1000000000000 sec | 10-12sec |
The speed of a computers is generally measured in MIPS (Millions of Instructions Per Seconds)
2) Accuracy:-Computer is basically 100% accurate machine .It gives accurate result provided correct data are given as input .If we give wrong or garbage data as input,the processed result will also be wrong or garbage.This is also knowns as ‘Garbage –In Garbage –Out ‘(GIGO).The output is dependent on the given input .The mistakes in the calculations of computer is due to human errors to data and and for instructions.
3)Dilligence:-A computer can perform required tasks repeatedly with same speed,accurancy and efficiency.It never gets tried or bored doing a work.So computer is diligent machine.
