Characteristics of computer

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 person in your neighborhood . For this you have to add income from sources for all persons on a day to day basis and find out the average each one of them how long will it take for you to do this?One day,two day or one week?Do you know your small computer can finish this work in few seconds? The weather forecasting that you see everyday on T.v is the result of compilation and analysis of huge amount of data on temperature,humidity, pressure ,etc.of various places on computers It take few minutes for the computer to process this huge amount of data and give the result.

You will be surprised to know that the computer can perform millions of instructions and even more per second.Therefore we determined the speed of computer in terms of microsecond or nano second from this you can imagine how fast your computer performance work.

Accuracy

Suppose someone calculates faster but commits alot of errors in computing.Such result is useless.there is another aspect.Suppose you want to divide 15/7.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.Someone else may go up to 9 decimal places and say that the result is 2.142857143 Hence,In addition to speed,the computer should have accuracy and 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 incorrect 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 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 have 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 this data.

No feeling

it does not have feelings or emotions, taste ,knowledge.It does not get tired even after long hours of work.It does not distinguish between user.

Storage

The computer has an inbuilt memory where it can store a large amount of data you can also store data in secondary storage divisor such as floppies.Which can be kept outside your computer and can be carried to other computer.
