Define computer and explain it's main …

Definition: The computer is an electronic device. It is known as an electronic device because it runs through electricity. It takes input, processes it and gives desired results. The results of the computer system are also known as output.

Computer characteristics

1. Speed: The computer is a much faster device. A computer machine can solve very complex problems faster than a person. It gives results within a second. Now a day, the computer can solve not only a single problem but also multiple problems within very less time.
2. Data Storage: A computer system can store a large amount of data for a long time period. The data can be store in internal as well as external devices. The internal device of data storage is Hard disk and external storage devices are Pen drive, External Hard disk, etc.
3. Accuracy: Computers can generate reliable results with high computational speed. If the input is right then only the appropriate output will be generated. The computer never gives inaccurate results; if results are inaccurate it means inputted data was erroneous.
4. Versatility: A computer is a versatile machine that can perform different types of jobs with the same accuracy rate.
5. Diligence: Computers never get tired. As humans get tires when he works regularly but the computer can perform tasks over and over again, with the same outcome, and it does so without tiring.
6. No IQ: It performs a task that is exactly as directed by the user because it does not have its intelligence.
   Reliable: Consistency refers that a computer is a reliable machine, as it always gives consistent results.
