Characteristics of a Computer

Following are the important characteristics of a computer:

• Speed
  
• Accuracy
  
• Data storage
  
• Efficiency
  
• Automation

Speed: Computer is a very fast speed device. The speed of a computer is normally measured in milliseconds, microseconds, nanoseconds and pico seconds. Computer can do the amount of work in a few seconds that a human being does in an entire year.

Accuracy: Performing a task exactly as it was instructed is called accuracy. The accuracy of a computer is always high and the degree of accuracy of a particular computer depends upon its design. But for a particular computer, each and every calculation is performed with the same accuracy.

Data Storage: As human being acquire new knowledge, the brain subconsciously selects what it feels to be important and worth retaining in its memory and relegates unimportant details to the back of the mind or just forgets them

Efficiency: Efficiency is one of the most wonderful things about the computer. Computer can perform multiple tasks simultaneously. For example preparation of the result of examination, communicating on network and retrieval of information etc.

Automation: Computer can repeat any operation for more than once with a single instruction. Once instruction set is fed, then it can work automatically without the intervention of human being e.g ATM, which is used in banking for deposits and withdrawal of cash
