This document provides an overview of computers including definitions, components, generations, software types, programming languages, number systems, and operating systems. It defines a computer as an electronic device that takes input, processes data, and provides output. The key components are described as the central processing unit, keyboard, mouse, and monitor. Generations of computers and some examples from each generation are also mentioned. The document discusses system software, application software, embedded software, and open source software. It concludes with brief descriptions of common number systems and operating systems like Windows and Linux.

4. Basic Information
Of
Computer
Our Topic Is

5. Hey Jerry
What is computer?
Just Wait

6. The word computer comes from the word
“Compute” which means “to calculate”.
Computer is a electronic device that takes data
as a input, process those data and then store or
show those data as a output.

7. Here we will see that
How does a computer work?
Input
(Material Raw) Processing Output
( Result)

8. Features
SPEED
ACCURACY
STORAGE
DILIGENCE
VERSATILITY
POWER OF REMEMBERING
NO IQ
NO FEELING

9. Components of computer
??????????????
Don’t Worry

10. Computer itself a combination of different type of separate
electronic device. Computer only will be computer if it has INPUT
DEVICE, PROCESS UNIT, and OUTPUT DEVICE.
Central Processing Unit (CPU) :
It is heart and mind of the computer without this unit computer unable to process.
Keyboard :
This is an input device which is used to input the data into the computer.
Mouse :
This is also an input device which is used to input the data into the computer.
Monitor :
This is an output device which is used to show the result of the instructions.

11. Generation Of Computer
First Generation
(1940 – 1955)
Electronic Numerical Integrator and Computer
(ENIAC) , EDVAC.
Second Generation
(1956 – 1965)
IBM 1401
Third Generation
(1966 – 1975)
IBM System/360
Fourth Generation
(1976 – 1985)
Macintosh 128k
Fifth Generation
(1986 -till date)
PC

12. Now I am going to discuss about
Computer Software
Software is a logical programmer to
solve the complex problem.
System Software : This is special
type of software which is
responsible for handle the whole
computer system.
Application Software : This is
special type of software which is
used to solve a particular problem.
Embedded Software : This type of
software embedded with hardware
to do a specific type of job.
Open Source Software : This type of
software may be freely available and
can not be use in commercially. We
can modify, and use it under the
same license.

13. Now,
Computer Languages
Machine Level Language : This is low level
programming language. Computer or any
electronic device only understand this language.
i.e. Binary number i.e 0 and 1.
Assembly Level Language : This is a low level
programming language which is converted into
executable machine code by a utility programmer
referred to as an assembler.
High Level Language : High level language is a
programming language which is easily
understandable by human.
Interpreter : This is a convertor which converts
high level language programme to low level
language programme line by line.
Compiler : This is also a convertor which converts
whole high level language programme to low level
language programme at a time.

14. Oh, I can’t understand ,
What is number system?
No problem.
I am here to help you

15. Number System
Binary Number System : It
has only base 2 i.e 0 and 1
Octal Number System :
Base of octal is 8 i.e. 0, 1, 2,
3, 4, 5, 6, 7
Decimal Number System :
Base of Decimal is 10 i.e. 0 1
2 3 4 5 6 7 8 9
Hexadecimal Number
System : Base of this
number system is 16 i.e. 0 1
2 3 4 5 6 7 8 9 A B C D E F

16. What are you
doing, Tom?
Nothing. But I need some
idea about Operating System
I can help you

17. Windows: This is a Ownership Operating system and vendor is
Microsoft.
Windows 2007,
Windows vista,
Windows 2008 etc.
Linux : This is an open source Operating System such as ubuntu,
fedora, debian , mandriva, centOS etc.
Thank you Jerry
