a) High Speed :

v Computer is a very fast devices.

v It is capable of performing calculation of very large amount of data.

v The computer has units of speed in microsecond, nanosecond, and even the picosecond.

v It can perform millions of calculations in a few seconds as compared to man who will spend many months for doing the same task.

b) Accuracy :

v In addition to being very fast, computers are very accurate.

v The calculations are 100% error free.

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

c) Storage Capability :

v Memory is a very important characteristic of computers.

v A computer has much more storage capacity than human beings.

v It can store large amount of data.

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

d) Diligence :

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

v It can work continuously without any error and boredom.

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

e) Versatility :

v A computer is a very versatile machine.

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

v This machine can be used to solve the problems related to various fields.

v At one instance, it may be solving a complex scientific problem and the very next moment it may be playing a card game.

f) Reliability :

v A computer is a reliable machine.

v Modern electronic components have long lives.

v Computers are designed to make maintenance easy.

g) Automation :

v Computer is an automatic machine.

v Automation means ability to perform the given task automatically.

v 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.

f) Reduction in Paper Work :

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

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

i) Reduction in Cost :

v Though the initial investment for installing  a computer is high but it substantially reduces the cost of each of its transaction.

 

DISADVANTAGES OF COMPUTERS

a)  Ever changing Technology.

b)  Increased Manpower Cost.

c)   Computer Stops Responding.

d)  Viruses.

e)  Reduction in Employment Opportunity.

 

a) Ever changing Technology :

v The technology that is new today, may soon become obsolete. We need to regularly upgrade the hardware and software in a computerized environment. This involes additional time and cost.

b)  Increased Manpower Cost :

v The computer needs to be operated by skilled person. This has led to an increase in manpower cost for organizations. Due to the inherent risks, huge expenditure are made ensure data security.

c) Computer Stops Responding :

v At times the operating system of the computer may stop responding or functioning. Though this problem is generally solved by restarting the computer, but sometimes you may have to take the support of the technician.

d) Viruses :

v The thread of virus and malware attack always remains in the computerized environment. To cope up with these risks, various antivirus software are available in the market. If you are using a good antivirus, you are almost sure that your private information and other sensitive data are secured.

e) Reduction in Employment Opportunity:

v The introduction of computers has negatively impacted the employability of computer illiterate people.
