characteristics / features of computer system

A computer is an electronic device, which take data as input , process it and finally display the output or its saves for the feature use. every computer have unique features or characteristics. The following are the some of the characteristics of a computer system.


  • Speed
  • Accuracy
  • Automation 
  • Diligence
  • Versatile
  • Memory 
  • No IQ
  • Economical 
  • Creatively developable  
  • Supports any language 
  • User friendly 
  • Networking ability 

Speed: Computers can perform millions of operations per second as compared with human being. The speed of computer is usually given in nanoseconds and picoseconds, where 1 nanosecond = 1x10 power -9 and 1 picosecond = 1x10 power -12 seconds.

Accuracy: A computer is a very fast, reliable, and robust electronic device. It always give accurate results, If provided the correct data and set of instructions are input to it. If your fed the incorrect data / program as input then the results contain errors.

Automation: Besides being very fast and accurate, computers are automatable devices that can perform a task without any user intervention. The user just needs to assign the task to the computer, after which it automatically controls different devices attached to it and executes the program instructions.

Diligence: Unlike humans, computers never get tired of a repetitive task. It can continually work for hours without creating errors. Even of a large number of execution are needed, each and every execution requires the same duration, and is executed with the same accuracy.

Versatile: versatility is the ability of being flexible. Today's, computers are used in our daily life in different fields.

Memory: Similar to humans, computers also have memory. Computers memory can be divided into two types primary memory and secondary memory. The may be expanded.

No IQ: Although the trend today is to make computers intelligent by inducing artificial intelligence (AI) in them, they still do not have any decision making ability of their own. Thus, their IQ level is zero. They need guidance to perform various tasks.

Economical: Today, computers are considered as short term investment forms achieving long term gains.
