Advantages of Computers
Following are certain advantages of computers.
v High Speed
@ Computer is a
very fast device.
@ It is capable
of performing calculation of very large amount of data.
@ The computer
has units of speed in microsecond, nanosecond, and even the picosecond.
@ It can perform
millions of calculations in a few seconds as compared to man who will spend
many months to perform the same task.
v Accuracy
@ In addition to
being very fast, computers are very accurate.
@ The
calculations are 100% error free.
@ Computers
perform all jobs with 100% accuracy provided that the input is correct.
v Storage Capability
@ Memory is a
very important characteristic of computers.
@ A computer has
much more storage capacity than human beings.
@ It can store
large amount of data.
@ It can store
any type of data such as images, videos, text, audio, etc.
v Diligence

v Versatility
@ A computer is a
very versatile machine.
@ A computer is
very flexible in performing the jobs to be done.
@ This machine
can be used to solve the problems related to various fields.
@ At one
instance, it may be solving a complex scientific problem and the very next
moment it may be playing a card game.
v Reliability
@ A computer is a
reliable machine.
@ Modern
electronic components have long lives.
@ Computers are
designed to make maintenance easy.
v Automation
@ Computer is an automatic
machine.
@ Automation is
the ability to perform a given task automatically. Once the computer receives a
program i.e., the program is stored in the computer memory, then the program
and instruction can control the program execution without human interaction.
v Reduction in Paper Work and Cost
@ The use of
computers for data processing in an organization leads to reduction in paper
work and results in speeding up the process.
@ As data in
electronic files can be retrieved as and when required, the problem of
maintenance of large number of paper files gets reduced.
@ Though the
initial investment for installing a computer is high, it substantially reduces
the cost of each of its transaction.
Disadvantages of Computers
Following are certain disadvantages of computers.
v No I.Q.
@ A computer is a
machine that has no intelligence to perform any task.
@ Each
instruction has to be given to the computer.
@ A computer
cannot take any decision on its own.
v Dependency
