Characteristics of Computer
Characteristics of Computer


  • The multipurpose of a computer depends on its speed.
  • A computer can perform several billion calculations in a few seconds.
  • Computer speed is measured in MIPS.

The computation speed of the computer is as follows
Milliseconds - 1 Thousand Seconds
Microseconds - 1 million seconds
Nanoseconds - 1 billion of seconds
Pico seconds - 1 trillion of seconds

Computers that work up to nanoseconds, picoseconds are currently available


  • The error rate is zero, even when the computer calculates its excessive capacity.
  • If the data is entered into the computer, the result obtained will be absolutely accurate.

The computer operates on the principle of garbage in garbage out. It means to say that the output will be the same as the input you give on the computer. That is, if you have given the correct input, then the result will also be correct and if you have given the wrong input then the result will also be false.


  • Once instructions are given, the computer automatically starts its operation on it.
  • The possibility of human intervention during the calculation is negligible. Although instructions are given to humans to work by the computer, once ordered, it can work non-stop.


  • A human's ability to remember is very weak, but the computer's capacity can be reduced or increased as needed.
  • The ability to store data in a computer system is very high.
  • Computers can store millions of vegetables in a lot of workplaces.

Computer storage units are as follows
Bit - Any data in a computer is saved in 0 or 1 form. 0 and 1 are called binary digits for short, it is also called a bit. The smallest unit of storage is a bit.

The computer uses two types of memory

  • Internal memory

  • It is a part of the Central Process Unit. It has the capability of storing data

  • External memory

  • While unlimited data and information can be stored by external memory such as - floppy, magnetic tape, optical disk, CD ROM, pen drive, memory card, etc.


  • A computer can do multiple tasks at the same time. Such as users can play songs, work on documents, search for any documents on a hard disk, surf the internet, use software, calculate, etc.


  • Computers can accelerate with the same speed and accuracy without fatigue or boredom.
  • A computer is a machine, it does not refuse to work and works with the same stability for hours.
  • But on the other hand, a human being can easily become tired with the same task. Repeatedly lose his concentration, speed, and accuracy because man suffers from fatigue, idleness.


  • A computer is a reliable machine, because many organizations, organizations, and companies are highly dependent on computers because of the reliability of computers.
  • Computer memory is more powerful. The entire computer-connected process is reliable.

Due to the reliability of the computer, you can store a large amount of data and you can use your data at any time and any time and without any restrictions.

Low cost and low size

  • With the advancement in the development of computer hardware and software technology, the cost of computers has decreased significantly and reached most humans.
  • Due to low cost and low computer size, it was used by hospitals, institutes, government sectors, companies, and users.

No Feeling and No IQ

  • Computers only work according to the guidelines, they do not have the ability to think nor can they do any work according to emotions.


  • A computer can be made confidential using passwords.
