Basic Information Of

Computer

Our Topic Is

What is computer?

Hey Jerry

Just Wait

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.

Input(Material Raw)

Processing Output( Result)

Here we will see that

How does a computer work?

Components of computer??????????????

Don’t Worry

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.

Generation Of Computer

First Generation

(1940 – 1955)Electronic Numerical

Integrator and Computer (ENIAC) , EDVAC.

Second Generation

(1956 – 1965)

System/360

Fourth Generation

(1976 – 1985)

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.

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.

Oh, I can’t understand , What is number system?

No problem. I am here to help you

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

What are you doing, Tom?

Nothing. But I need some idea about Operating System

I can help you

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.
