The article will help us to understand the technicalities of Computer function. Beginners must know this, it is more useful to design the career in any of this parts. Two technical parts make a computer ready to use.
Software
Hardware: Hardware is a physical component of computer, like in earlier blogs we have already discussed about the Input device, CPU, Out Device.
Parts of Computer:
- Keyboard - Keyboard generally (with 105 Keys) is used QWERTY mechanism, this mechanism is nothing but keys are set on board as like manual typewriter key board. Keys on the keyboard are - Numerical keys (0-9), Alphabetical Keys (A-Z), special characters (@#$%^&*), function keys (F1 - F12) and other supporting key like caps lock, tab, shift key, space bar, delete key and so on.

Hello Readers,
Functionality of Computer
By the way we have understood about the term computer and basic structure, parts of computer. Overall by this we get the rough idea about the computer. Today we shall learn about the functioning of computer.
Before starting to functioning of computer, lets understand some basic terms generally used:
- Input: Putting or providing the information.
- Information/instruction: It is a piece of sentences or commands provided to computer to process.
- Process: calculating, drafting the information in prescribed form, formulating the information is known as processing the information
- Data: Data is processed information.
- Output: Output is final result received after processing.

What is Computer?
How does it works?
Why it is more useful in our life?
---------------------------------------------------------------------------------
Should I learn computer or is it necessary to learn the usage of computers, what charges will I have to pay? What are the terms Hardware and Software commonly used? Many of us find cribbing with such type of common question and the answer is learn computers and shoot out the trouble.
Now Learning Computer means - to learn operation of computer. First chapter is History (which is already covered in previous post), further we shall study about computer, how does it works.
Computer is an electronic device which is used to process the information and transform in data. the term information is used prior to processing and lastly the word data is used, it means before processing the information (raw material) after processing it turns into data (transcribed form). Initially mechanism of computer machine is divided in to 5 major parts and those are-
The basic structure of computer is-

Computer is a mechanical device used for computing the jobs, mathematical problems, it is being used in many sectors from small scale to large scale.
History of Computers
The Concept of Computer lies in Abacus (a computing slate) 150 B.C. The word computer was enforced late 1600 AD. In 1837, the then renowned scientist Charles Babbage (known as father of computers) was the first man to design the computer with the concept of manufacturing unit (Inputing raw material, processing the raw material as per our requirement and turn the raw material into finished goods) by using programmable concept of computing. Basically the need of invention of computers started in late 1890, to process the data of census in United States of America. and the generation of computers started. Meanwhile many other scientist made efforts to design a user-friendly computing device. The actual era started after 1945. Categorically Computer History is divided into generations, each generations made computers relatively more familiar than previous generation. Lets take the journey by understanding each generation one-by-one.
First Generation: (1945-60) Vacuum Tubes The first computer was developed in mid on 20th century 1940-45, these computers consumed large amount energy, area, hundreds of people to operate the machine, it was built with the help of Vacuum Tube which use to produce large amount of heat and was not user friendly to operate. Vacuum Tube used to damage frequently. In this generation the concept was sucessful but the device was not useful.

This is an great opportunity for me to share basic computer knowledge
at free to all the beginners. We will learn computers in and out topic-wise in understandable language. Generally, maximum citizens are aware of computers, but most of developing countries very few people knows about computers, in India, Government of India has taken great efforts to make citizens computer literate at basic level. Computer is man-made machine, but proved to be faster than man. Learning computer has become an essential part of every individual. As we all see around us how computer technology has made our life easier. In our regular life we computer is used in almost all the sector from small business to large scale industries, space, medical and engineering fields, statistical reporting, generating reports. Computers can maintain large amount of data for long period of time and again can be retrieved when ever required. Due to computer world has come closer, one can simply sent the information to other part of world in just fraction of minute. Computer has proved a great revolution for next generation.
