Characteristics of a Computer
1) Speed:
A computer is a very fast device. It can
perform in few seconds, the amount of work that a human being can do in an
entire year. The speed of a computer measure in microseconds(10-6),
nanoseconds(10-9) and picoseconds(10-12). A powerful computer is capable of
performing several billion arithmetic operation per second.
2) Accuracy:
Computer is very accurate
device. The accuracy of a computer is principle high. The degree of accuracy of
a particular computer depends upon it’s design. Computer done very calculation
with same accuracy. Errors can occur in a computer, However, these problem are
mainly due to human rather than technological weaknesses.
3) Automatic(Automation):
A machine is no
sooner than done to be automatic if it, works by itself without human
intervention. Computer are automatic machines, because one started on a job,
they carry on, until the job is finished, without any human assistance.
However, computer being machines can not start them selves. They cannot go out find their own problems and solutions. They have to be instructed.
4) Diligence:
Computer has unlike human
beings. A computer is free from dullness and lack of concentration. It can
continuously work for hours without creating any error human beings in doing
regular types of jobs, which requires great accuracy. Computer can perform the
number of calculation with exactly the same accuracy and speed as the first
one.
5) Versatility:
Versatility is a most important characteristic of
computer. It means the capacity to perform completely different type of work.
You may use your computer to prepare payroll slips. Next moment you may use it
for inventory management or to prepare electric bills. A computer is capable of
performing almost any task, if the task can be reduced to series of logical
steps.
6) Memory(Power of Remembering):
Computer has a brain, but unlike human (Man)
beings. A computer can store data and information. And recalled as long as
you require it, for any numbers of years. Because of it’s secondary storage
capability. A data and information can be retrieved as long as desired by the
user and can be recalled, as when required. The information recalled would be
as accurate as on the day when it was fed to the computer.
7) No. I.Q.(Intelligence Quotient) :
A computer
is not a magical device. It is no intelligence of it’s own. User can determine,
what tasks will the computer perform. So a computer cannot take its own
decision as you can. (A computer can not take it own decision in this regard.).
8) No Feelings:
Computer has no feelings. They have no emotions, because they
are machine. Computer is not like human heart and soul. Computer cannot make
such judgments on their own. Their judgment is based on the instructions given
to them in the from of programs, that are written by us.
9) Cheaper rate:
Computers are short term investment
in order to achieve a long term gain. Though the investment is high they reduce
the cost of each and every transaction. They reduce man power and leads to an
elegant and efficient way for computing various tasks.
