The characteristics of computers that have made them so
powerful and universally useful are speed, accuracy,
diligence, versatility and storage capacity. Let us discuss them
briefly.
- Speed
Computers work at an incredible speed. A powerful computer
is capable of performing about 3-4 million simple instructions
per second. - Accuracy
In addition to being fast, computers are also accurate. Errors
that may occur can almost always be attributed to human
error (inaccurate data, poorly designed system or faulty
instructions/programs written by the programmer) - Diligence
Unlike human beings, computers are highly consistent. They
do not suffer from human traits of boredom and tiredness
resulting in lack of concentration. Computers, therefore, are
better than human beings in performing voluminous and
repetitive jobs. - 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. - Storage Capacity
Today’s computers can store large volumes of data. A piece
of information once recorded (or stored) in the computer,
can never be forgotten and can be retrieved almost
instantaneously.
