3. Functions of computer:-
 Receive input
 Process information
 Produce output
 Store information

4. Receive Input
• Input devices, such as
a keyboard or mouse
accept data

5. Process Information
 The central processing unit (CPU) interprets and
executes program instructions to process information,
perform arithmetic calculations, and make logic-based
decisions.

7. Store Information
 Memory (RAM) holds data temporarily for use by the
CPU and secondary storage devices, such as a hard
drive, CD, DVD, or USB flash drives store data for
long-term retrieval.

8. Produce Output
 Output devices, such as a
monitor or printer, send
information from the
computer to the outside world
