Advantage & Disadvantage of Computer

Advantage and disadvantage of computer

What is the advantage and disadvantage of computer in today’s arena?

Ans: Computer is an electronic data processing device which

·         Accepts and store data input,

·         Process the data input, and

·         Generates the output in a required format

Computer

Advantage:

Following list demonstrates the advantage of computer in today’s arena.

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 calculation in a few seconds as compared to man who will spend many months for doing this task.

Accuracy:

·         In addition to be very fast, computers are very accurate.

·         The calculation are 100% error free.

·         Computers perform all jobs with 100 % accuracy provided that correct input has been given.

Storage capability:

·         Memory is a very important characteristic of computers

·         A computer has much more storage than human beings

·         It can store large amount of data

·         It can store any type of data such as image, videos, text, audio and many others.

Diligence:

·         Unlike human beings, a computer is free from monotony, tiredness and lack of concentration.

·         It can work continuously without any error and boredom.

·         It can do repeated work with same speed and accuracy.

Versatility:

·         A computer is a very versatile machine

·         A computer is very flexible in performing the jobs to be done.

·         This machine can be use 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.

Reliability:

·         A computer is a reliable machine

·         Modern electronic components have long lives

·         Computer are designed to make maintenance easy

Automation:

·         Computer is an automatic machine

·         Automation means ability to perform the given task automatically

·         Once a program is given to computer i.e. stored in computer memory, the program and instruction can control the program execution without human interaction.

Reduction in paper work:

·         The use of computers for data processing in an organization leads to reduction in paper work and results in speeding up a process.

·         As data in electronic files can be retrieved as and when required, the problem of maintenance of the large number of paper files gets reduced.

Reduction in Cost:

·         Though the initial investment for installing a computer is high but substantially reduce the cost of each of its transaction.

Disadvantage:

Following list demonstrates the disadvantage of computers in todays arena.

No.1Q:

·         A computer is a machine that has no intelligence to perform any task.

·         Each instruction has to be given to computer.

·         A computer can not take any decision on its own.

Dependency:

·         Its functions as per a user’s instruction, so it is fully dependent on human beings.

Environment:

·         The operating environment of a computer should be dust free and suitable.

No feeling:

·         Computers have no feelings or emotions.

·         It can not make judgement based on feelings, taste, experience and knowledge unlike a human being.
