The important characteristics of a computer are as follows:
1. Speed Computer processes data at a very high speed. It is much
faster than human beings. A computer can perform billions of calculations in a second.
Computer speed is measured in Mega Hertz (MHz) or Giga Hertz (GHz). For example, the
process of multiplying 750 and 927 can take one or two minutes if it is performed by human
beings. However, a computer can perform millions of such calculations within a second. 2. Reliability Computer is very reliable. The electronic in modern rarely
break or fail. 3. Accuracy Accuracy means that the computer provides results without
any errors. Computer can large amount of data and produce results accurately. The
result can be wrong data given to computer is not correct. Suppose the average
marks of a class required. There can be a chance of mistake in the result if
it is performed by human However, a computer can produce this result very accurately
and quickly. 4. Storage Computer can store a large amount of permanently. People can
use this data at any time. The user can store any type of data in The storage
capacity of computer is increasing rapidly. A computer can store
thousands of books easily. 5. Versatility Computer is a versatile machine. It can perform different
types of tasks. That is why it is being used in every field of life. Computer is used in hospital,
bank, office and at home. A user can play games, listen to music, watch movies and use
the Internet using a 6. Consistency Computer works in a consistent way. It does not lose
concentration due to heavy work. It does not become tired or bored. Computer performs all
jobs with equal attention. 7. Communication Most computers today have the capability of communicating
with other computers. We can connect two or more computers by a communication
device such as modem. These computers can share data, instructions, and information. The
connected computers are called network. We can communicate with other people in the world
using network like Internet 8. Recalling A computer can recall the stored data and information as and
when required. The data stored in the computer can used at a later time. The computer
can recall the required data in a few seconds. 9. Control Sequence A computer works strictly according to the given
instructions. It follows the same sequence of execution that is given in a program. 10. Cost Reductions We can perform a difficult task in less time and less cost.
For example, we may have hire many people to handle an office. The same work can be
performed by a single person with the help of computer. It reduces the cost.
