Computer is a group of electronic devices used to process the data.
The characteristics of a computer are:
4. Accuracy5. Automation 6. Functionality 7. Tirelessness
1. Speed 2. Reliability 3. Memory capacity
![Page 36: Computer Can Classified in to Five Types](https://reader033.vdocument.in/reader033/viewer/2022061118/546a400fb4af9fd2038b4777/html5/thumbnails/36.jpg)
1.Speed: computer process the data at an unimaginable speed. The speed of the computer ranges up to Nano seconds.
2. Reliability: The next important characteristic of a computer is its reliability. we can always rely on the information given by a computer.
3. Memory capacity: The memory capacity of a computer is measured in in bits and bytes. Large amount of the data can be stored in computer and retrieved. Memory capacity of the computer ranges in Giga bytes.

4. Accuracy: Accuracy of the computer is very high it performs calculation with greater accuracy
in less time.
5. Automation: a computer allows automation for any process designed in the from of a program. A program can be executed any number of times to repeat the process.

6. functionality: computer can performs many kinds
of jobs. They not process the data but also can be
Used for plying music, movies, and printing jobs.
It finds its applications in all most all the fields.
7. Tirelessness: A computer never gate tired.
