Computer
full form of computer
Commonly operated machine particularly used for technology education and research.
computer is a Electronic device that Accept input , Store input in memory and Process by CPU
Produce finaly Output on monitor.
Data - row fact name, number, image etc
Processing - manipulation of data
Information - meaningful data , processed data
Numeric data :- 1234
Alphanumeric data :- employ address
