1. What is COMPUTER?
Computer is a General purpose electronic machine or device.
Program to perform Arithmatic (mathematical +,-,*,/) and logical(<,>=,/=) Operation.
Takes data and instruction as Input and Process to produce result as output.
Common Operating Machine Particularly Used for Trade, Education, and Research.
Common Multiple Purpose Terminal.
Computer is called computer system because it has perform operation.
Computer has two main parts:
1. Hardware
2. Software
1.Hardware:
Hardware is the physical part that can be see and touch.
Example: Mouse, Keyboard, Moniter.
Hardware are two types:-
i) Input Device
ii) Output Device
i) Input Device:
It is the physical part of the computer which is use to enter data and instruction

2. into the CPU.
Example:- Mouse, Keyboard etc.
ii) Output Device:-
It is the physical part of the computer which is use to get result as output from
the CPU.
Example:- Moniter, Printer, etc.
2. Software:
Software is a collection program which is a collection program which is design to
perform perticular operation.
Software can't be seen or touch.
Software are two types:-
i) System Software
ii) Application Software
i) System Software:
Necessary to boot operate the computer system.
Designed to run hardware.
Provide plateform to Application software.
Operating system, untilites, Translator program.
Example: Windows, Antivirus, Computer etc.
ii) Application Software:
Designed to perform a specific function or task.
Help the users to perform sinle or multiple tasks.
Words processing, accounting, games, media player.
Example: MS-Office, Tally Jardians, VLC etc.
In Computer CPU (Central Processing Unit) takes Input data and instruction using input
device (eg- Keyboard, Mouse) to process by CPU to produce result as output and get it
using device (eg- Moniter, Printer) output can be store in storage device (eg- Harddisk,
Pendrive) for the future use.

3. BOOTING
The process of starting of a computer in which Operating System is Successfully
loaded into the computer (in RAM)- e .I. OS is loded into Primary memory (RAM).
Operating System
It is a System software that help to boot the computer the overall
computer system.
i) It provide interface to the user to link with the computer.
ii) It provide all the software and hardware parts of the computer.
iii) It provide plateforme to the application Software.
Example: Windows (XP,7,8,10) LINUX.
Desktop = It is the first screen when the computer system open in the moniter.
Icon = Icon is the small picture that represent file, folder, software in the desktop.
Start Botton:-
It is the button on left bottom corner of the computer system that list all the
programme of the computer system.
Harddisk :- Harddisk is physical storage are where we can store our files.
Computer Icon on desktop
It is the where logical partition of Harddisk are available in the form of drive.
For Example – C: Drive, D: Drive, E: Drive
