What are the characteristics of computers?

Answer 1

Characteristics of Computer

Speed

A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations. Computers can process millions (1,000,000) of instructions per second. The time taken by computers for their operations is microseconds and nanoseconds.

Accuracy

Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy.

Diligence

A computer can perform millions of tasks or calculations with the same consistency and accuracy. It doesn’t feel any fatigue or lack of concentration. Its memory also makes it superior to that of human beings.

Versatility

Versatility refers to the capability of a computer to perform different kinds of works with same accuracy and efficiency.

Reliability

A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result.

Automation

Computer performs all the tasks automatically i.e. it performs tasks without manual intervention.

Memory

A computer has built-in memory called primary memory where it stores data. Secondary storage are removable devices such as CDs, pen drives, etc., which are also used to store data.

Answer 3

The only characteristic of a computer is the ability to compute. The human brain is a computer. A thermometer is a computer. IBM Sequoia is a computer. The only thing they have in common is their ability to compute. That is why we call them computers.

All other characteristics are only characteristic to a specific type of computer, whether it be biological, analog or digital, or any combination of the three.

Previous (wrong) answer [and reasons]

Characteristic's of computer are:

1. Automatic machine. [Mechanical computers do not work by themselves.]
2. Fast device. [A bullet is a fast device, but is it a computer?]
3. Accurate. [The human brain is far from accurate.]
4. Diligence (free from tiredness). [The human brain requires rest.]
5. Versatility. [Analog computers are not versatile. Most are single purpose.]
6. High power of remembering. [Humans are forgetful.]
7. No IQ. [Only the dead have no IQ.]
8. No feelings. [The human brain can process emotions.]

A computer transforms information according to an algorithm. It accepts input, produces output, and has some form of memory or state. The electrical device on a desk which readily comes to mind for most people is only one specific kind of computer. Mechanical computers have been partially constructed. Brain tissue is at least partially a computer. The universe can be considered a computer in which the laws of physics represent a program being executed on hardware composed of fundamental particles.

Answer 4

As we all know computer is an electronic device which stores, reads and processes the data or information or produce the meaningful results/output. Computer is a powerful machine that assists us in our daily life. what makes computer unique than humans is its specific characterstics, which can be enumerated as Speed, Storage , Accuracy , Ability to operate automatically , diligence , Scientific approach and versatility. Speed The speed of a computer is increadibly faster than what man can possibly record or calculate normally. Storage One of man's failing is perhaps his inability to remember and "store" large volumes of information in his brain. The computer is capable of overriding this deficiency as it can store. Accuracy and Reliabilty Inspite of high speed, the computers are quite accurate and reliable in their calculations. the accuracy of operation of a computer is always 100%. computer is only a machine and does not make error on its own. it is thus reliable. Automatic Once the process has been initiated, computer is quite capable of functioning automatically. it does not require a prompt from an operator at each stage of the process. Deligence/Endurance Man suffers from physical and mental fatigue, lack of concentration and laziness which do not permit him to carry on his task at the same level of speed and accuracy through the entire day. The computer , on the other hand is capable of operating at exactly the same level of speed and accuracy even if it has to carry out the most voluminous and complex operations for a long period of time. Scientific Approach The entire approach to solving problems is highly scientific, objective and sequentially carried out, leaving no room for emotional and subjective evaluations made by man, which are sources of potential error and unjustified results. Versatility The wide use of computers in so many areas in day-to-day life is an ample evidence of its versatility. Hagerie Hailu from MSD

Answer 5

Speed: Computers work at very high speed and are much faster than humans. A second is very large time period time for computer. A computer can perform billions of calculations in a second. The time used by a computer to perform an operation is called the processing speed. Computer speed is measured in Mega Hertz (MHz).

Storage: A computer can store a large amount of data permanently. User can use this data at any time. We can store any type of data in a computer. Text, graphic, pictures, audio and video files can be stored easily. The storage capacity of the computer is increasing rapidly.

Processing: A computer can process the given instructions. It can perform different types of processing like addition, subtraction, multiplication and division. It can also perform logical functions like comparing two numbers to decide which one is the bigger etc.

Accuracy: Accuracy means to provide results without any error. Computers can process large amount of data and generate error-free results. A modern computer performs millions of operations in one second without any error.

Communication: Most computers today have the capability of communicating with other computers. We can connect two or more computers by a communication device such as modem. These computers can share data, instructions, and information. The connected computer are called network.

Answer 6

Speed

As you know computer can work very fast. It takes only few seconds for calculations that we take hours to complete. Suppose you are asked to calculate the average monthly income of one thousand persons in your neighborhood. For this you have to add income from all sources for all persons on a day to day basis and find out the average for each one of them. How long will it take for you to do this? One day, two days or one week? Do you know your small computer can finish this work in few seconds? The weather forecasting that you see every day on TV is the results of compilation and analysis of huge amount of data on temperature, humidity, pressure, etc. of various places on computers. It takes few minutes for the computer to process this huge amount of data and give the result.

You will be surprised to know that computer can perform millions (1,000,000) of instructions and even more per second. Therefore, we determine the speed of computer in terms of microsecond (10-6 part of a second) or nano-second (10-9 part of a second). From this you can imagine how fast your computer performs work.

Accuracy

Suppose some one calculates faster but commits a lot of errors in computing. Such result is useless. There is another aspect. Suppose you want to divide 15 by 7. You may work out up to 2 decimal places and say the dividend is 2.14. I may calculate up to 4 decimal places and say that the result is 2.1428. Some one else may go up to 9 decimal places and say the result is 2.142857143. Hence, in addition to speed, the computer should have accuracy or correctness in computing.

The degree of accuracy of computer is very high and every calculation is performed with the same accuracy. The accuracy level is determined on the basis of design of computer. The errors in computer are due to human and inaccurate data.

Diligence

A computer is free from tiredness, lack of concentration, fatigue, etc. It can work for hours without creating any error. If millions of calculations are to be performed, a computer will perform every calculation with the same accuracy. Due to this capability it overpowers human being in routine type of work.

Versatility

It means the capacity to perform completely different type of work. You may use your computer to prepare payroll slips. Next moment you may use it for inventory management or to prepare electric bills.

Power of Remembering

Computer has the power of storing any amount of information or data. Any information can be stored and recalled as long as you require it, for any numbers of years. It depends entirely upon you how much data you want to store in a computer and when to lose or retrieve these data.

No IQ

Computer is a dumb machine and it cannot do any work without instruction from the user. It performs the instructions at tremendous speed and with accuracy. It is you to decide what you want to do and in what sequence. So a computer cannot take its own decision as you can.

No Feeling

It does not have feelings or emotion, taste, knowledge and experience. Thus it does not get tired even after long hours of work. It does not distinguish between users.

Storage

The Computer has an in-built memory where it can store a large amount of data. You can also store data in secondary storage devices such as floppies, which can be kept outside your computer and can be carried to other computers.
