2. What is a computer?
● A computer is an electronic device which
takes input data from the user, then
processes it and returns the required output
data.
● Data can be number, text, images etc on
other hand information is data that gives
meaning in specific context and ordered way.
● A computer can work without getting tired and
without making mistakes.

3. Understanding the functions of a computer
● Any information or data Entered in a
computer for processing is called Input.
● Any information processed by and sent
out from a computer is called Output.
● processing is the actions a Computer
performs when it receives information
● storing is the action of saving information
for later use.
● Input = Entering information in
computer
● Output = Getting result from
computer
● Processing = Actions performed
on information by computer
● Storage = Saving information in
computer

5. Components of
a computer
● There are 2 basic components of computer:
1. Hardware
2. Software
● A hardware is the physical part of a computer
system which we can touch and can see. On
the basis of work these hardware parts are
divided into 2 parts:
a. Input Devices - Sends information to
computer.
b. Output Devices - Display results/output from
the computer.

6. Components of
computer
● Software is a set of instructions that tells a
computer what to do or how to perform a task.
● Take an example of vehicle and the driver, the
vehicle i.e. the car is hardware and the driver is
the software.
● There are two types of software:
1. System software: type of software that is
designed to run a computer’s hardware and
application programs. Example - Operating
system.
2. Application software: type of software used for
performing tasks such as paint.

8. What did you learn?
● A computer is an electronic device which takes
input data from the user, then processes it and
returns the required output data.
● Input refers to entering information/ data.
● Output is displaying of result.
● Processing means performing an action on
entered data.
● Storage means saving the data in computer.
● Functions of a computer:
a. A computer takes input from user
b. Process operations on it
c. Stores the data
d. Display the output.

9. What did you learn?
● There are two components of computer i.e. hardware
and software.
● Hardware is physical components of computer that one
can see an touch. It can be further classified as input
devices and output devices.
● Software is set of instruction that tells hardware to do
stuff.
● Hardware and software are like car with a driver, car
being hardware and driver being software.
● Software is of two types
1.System software 2. Application software
