What are Charachteristics of Computer

Following are the important characteristics of a computer: 1. Speed Computers work at a very high speed. They are much faster than humans.

A computer can perform billions of calculations in a second. Computer speed is measured in Mega Hertz (MHz). 2. Storage A computer can store large amounts of data permanently. Users can use this data at any time later in future. 3. Processing A computer can process the given instructions. It can perform different types of processing like addition, subtraction, multiplication and division. It can also perform logical functions like comparing two numbers. 4. Accuracy Accuracy means the capability to provide results without any errors. Computer can process large amounts of data and produce 100% accurate results. 5. Recalling A computer can recall the stored data and information at any time, as and when required. 6. Control Sequence A computer processes data in a sequence according to the given instructions. 7. Consistency Computer works in a consistent way. It does not lose concentration due to heavy work. Computer performs all jobs with equal attention. 8. Communication We can connect two or more computers to share data and hardware (printer, hard disk, CD-ROM Drive). We can send messages and chat with other people in world through Internet. 9.

If a computer is given a program for addition it cannot perform subtraction by itself. 12. Cost Reduction Computer can reduce cost. We can do a work in less time and cost by computer. A single person, with computer, can do work of many people in an office. 13. Diligence Computer has the ability to work for long times without tiredness.
