What is computer?
Computer is an electronic data processing machine which takes the input store
the raw data process it with the help of Arithmetic logic unit (ALU) under the
supervision of control unit (CU) and give us output according to the instructions.
It’s save for the future use. The word computer is derived from a Latin word
(compute).
Functionalities of a computer
◦ Takes data as input.

, TAIYARI24HOUR.COM
◦ Stores the data/instructions in its memory and use them when
require
◦ Processes the data and converts it into useful information.
◦ Generates the output
◦ Father of computer-Charles babage(1826.) ◦
Modern father of computer-Allen turing.
◦ First digital or first modern computer- ENIAC Input:-
This is a process of entering data and program into the computer system.
Storage:-
The process of saving data and instruction permanently is known as storage.
Processing:-
The task of performing operation like arithmetic and logical operation is
called processing.
Output:-
This is the process of producing result from the data or the instructions
provided by the input device. The output is of three types’ soft copy and hard
copy.
Soft Copy:-
These are the output which are being provided or displayed on screen for e.g.
monitor or projector.

Hard Copy:-
These are the output which is being provided on through the printer as an
output.
Voice Copy:-
These are the output which is being provided on through the Speaker as an
output.
