Characteristics of Computer
(Advantages)
- High Speed
- Accuracy
- Storage Capability
- Diligence
- Versatility
- Reliability
- Automation
- Reduction in Paper Work
- Reduction in Cost
• Computer is a very —- 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 for doing the same task.
High Speed
• 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 correct input has been given.
Accuracy
• 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 and many others.
Storage Capability
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
Diligence
• 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.
Versatility
• A computer is a reliable machine.
• Modern electronic components have long lives.
• Computers are designed to make maintenance easy.
Reliability
• Computer is an —– machine.
• ________ 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.
Automation
• 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 large number of paper files gets reduced.
Reduction in Paper Work
• Though the initial investment for installing a computer is high but it substantially
reduces the cost of each of its transaction.
Reduction in Cost
Characteristics of a computer (Disadvantages)
- No I.Q.
- Dependency
- Environment
- No Feeling
• A computer is a machine that has no intelligence to perform any task.
• Each instruction has to be given to computer.
• A computer cannot take any decision on its own.
No I.Q.
• It functions as per a user’s instruction, so it is fully dependent on human being
Dependency
• The operating environment of computer should be dust free and suitable.
Environment
• Computers have no feelings or emotions.
• It cannot make judgment based on feeling, taste, experience, and knowledge unlike a human being.
No Feeling
