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

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.
·         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.
·         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.
·         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.
·         A computer is a reliable machine
·         Modern electronic components have long lives
·         Computer are designed to make maintenance easy
·         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.
Following list demonstrates the disadvantage of computers in todays arena.
·         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.
·         Its functions as per a user’s instruction, so it is fully dependent on human beings.
·         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.
