Characteristics of computers

   

Characteristics:

       All computers have similar characteristics, which tells how computers are efficient to perform task. Computers have some Limitations also.

Speed:

    Computer can work very fast. It takes only few seconds for calculations on very large amount of data. Computer can perform millions (1,000,000) of instructions per second.

     We measure the speed of computer in terms of microsecond (10-6 part of a second) or nanosecond (10 to the power -9 part of a second).  

Accuracy: 

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

      The calculation done by computer are 100% error free, If we provide accurate input.

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.  

Automation:

   Computer is an automatic machine. It means the ability to perform a given task automatically after taken instruction.

       Once the Computer receives a program that means program stored in computers main memory, then instructions and data control the execution with out human interaction. 

Versatility:

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

Storage:

       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, how much data we 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 and irritation even after long hours of work. It does not distinguish between users.
