Characteristics of the Computer
The characteristics of computers that have made them so powerful and universally useful are:
1) Versatility
2) Storage
3) High Speed
4) Diligence
5) No IQ
6) Accuracy
7) Reliability
8) No Feeling
Let us discuss them briefly.
1) Versatility:-
Computers are versatile machines and are capable of performing any task as long as it can be broken down into a series of logical steps. The presence of computers can be seen in almost every sphere – Railway/Air reservation, Banks, Hotels, Weather forecasting and many more.
2) Storage :-
Storage capacity is another big characteristic of a computer. A computer can store large amount of data. This data can be used at any time and also from any location. The storage capacity of a computer is measured in Kilo Byte, Mega Byte, Gega Byte, Tera Byte.

3) High Speed :-
Computers work at an incredible speed. A powerful computer is capable of performing about 3-4 million simple instructions per second.
The speed of a computer at performing a single operation can be measured in terms of:
a) Milliseconds - One thousandth of a second (1/1000)
b) Microsecond - One millionth of a second (1/1000000)
c) Nanosecond - One billionth of a second (1/1000000000).
d) Picoseconds - One trillionth of a second(1/1000000000000).
b) Microsecond - One millionth of a second (1/1000000)
c) Nanosecond - One billionth of a second (1/1000000000).
d) Picoseconds - One trillionth of a second(1/1000000000000).
4) Diligence :-
A computer is free from tiredness, lack of concentration, fatigue, etc. It can work for hours without creating any error. If millions of calculations are to be performed, a computer will perform every calculation with the same accuracy. Due to this capability it overpowers human being in routine type of work.
5) No IQ :-
Computer is a dumb machine and it cannot do any work without instruction from the user. It performs the instructions at tremendous speed and with accuracy. It is you to decide what you want to do and in what sequence. So a computer cannot take its own decision as you can.

6) Accuracy :-
The degree of accuracy of computer is very high and every calculation is performed with the same accuracy. The accuracy level is 7 determined on the basis of design of computer. The errors in computer are due to human and inaccurate data.

7) Reliability :-
Computer output is generally very reliable, subject to the condition that the input data entering the computer should be correct and the program of instructions should be reliable and correct. Incorrect input data and unreliable programs give us computer errors and wrong results.

8) No Feeling :-
It does not have feelings or emotion, taste, knowledge and experience. Thus it does not get tired even after long hours of work. It does not distinguish between users.
