3. Charles Babbage is known as “The
Father of Computer”. The first use
of the word "computer" was
recorded in 1613 referring to a
person who carried out calculations,
or computations, and the word
continued with the same meaning
until the middle of the 20th century.
ENIAC was the 1st computer of
world.

4. Data is a collection of raw
facts, figures and symbols such
as
numbers, words, images, video
which is given to the computer
as the input. Computers
manipulate data to create
information.
Information is data that is

5. Software is a set of
programs, procedures, algorithms
and its documentation concerned
with the operation of a data
processing system.

6. TYPES OF
SOFTWARE
System software
System software is designed to
operate computer hardware to
provide basic functionality and to
provide a platform for running
application software.
Application software
Application Software is
developed to perform in any task
that benefits from computation.

7. The term hardware covers all of
those parts of a computer
that are tangible objects.

8. INPUT DEVICES
The devices which takes input are
called Input Device.
Example : Keyboard, Mouse, Joystick
etc.
OUTPUT DEVICES
The devices which gives output are
called Output Devices.
Example :
Printer, Speaker, Headphone etc.

9. TYPES OF
HARDWARE
Storage Devices
The devices used to store information
are called Storage Devices.
Example : Pan drive, Floppy etc.
Processing Devices
The devices used for processing
are called
Processing Devices.

10. The central processing unit (CPU)
contains electronic circuits that cause
processing to occur. The CPU
interprets instructions to the
computer, performs the logical and
arithmetic processing operations, and
causes the input and output
operations to occur. It is considered
the “brain” of the computer.
