Characteristics of Computer

  • Note
  • Things to remember

Computer is the most powerful machine in today's world. It has become the need in everyone's life. A computer can perform task very quickly and accurately. Computer has its own features and characteristics.
Some of the important characteristics of computer are described below:

Speed

Speed of computer maybe defined as the time taken by a computer to perform a task. It takes only a few seconds for the calculations that we take hours to solve. It works in the fraction of second. Most of the computers work on Micro and Nano second. Its speed is measured in term of MHZ (Mega Hertz) and GMZ (Giga Hertz).

Accuracy

The computers are the accurate machine that can perform large number of tasks without errors, but if we feed wrong data to the computer it returns the same wrong information called GIGO (Garbage In Garbage Out). The degree of accuracy in a computer is very high and every calculation is performed with same accuracy. The accuracy level is determined on the basis of design of computer. The errors in the computer are due to human and inaccurate data.

Diligence

The capacity of computer of performing repetitive task without getting tired is called diligence. A computer is free from tiredness, lack of concentration, fatigue etc therefore it can work for hours without creating any errors. Even if millions of calculations are to be performed, computer will perform every calculation with same accuracy.

Versatility

The capacity of computer of performing more than one task at the same time is called versatility of computer. Versatility means the capacity to perform different types of work completely.

Storage

Computer has mass storage section where we can store large volume of date for future use. Such data are easily accessible when needed. Magnetic disk, magnetic tape and optical disk are used as mass storage devices. The storage capacity of computer is measured in terms of Kilobyte (KB), Megabyte (MB), Gigabyte (GB), and Terabyte (TB).

Automatic

Computer is an automatic machine which works without the intervention of the user. The user is required to give the data and utilize the result but the process is automatic.

Processing

Large volume of data can be processed in great speed. During processing there are different types of operation such as input and out operation, logical and comparison operation, text manipulation operation etc.

Non-intelligent

Computer is a dumb machine which cannot do any work without the instruction of the user. The instructions are performed at tremendous speed and with accuracy. Computer cannot take its own decision and doesn't have feeling or emotion, taste, knowledge and experience etc.
