Introduction to Computer:-
The word compute is derived from the Latin word ‘computare’, was meaning "arithmetic, accounting". The Computer that means is that the digital device that stores data in memory mistreatment input devices and manipulate data to provide output in step with given directions.That is referred to as pc code (often referred to as simply software).

Computer Meaning in general term:-

Technically, a computer means to calculate or electronic programmable machine.Computer is employed to perform some sequence of directions in quick and correct manner. Computer receives input within the kind of digitalized information, using input devices like keyboard, mouse, joystick, scanner etc. It method supported a program directions to relinquish output. Two totally different kind of pc area unit exited: analog and information processing system.

• An analog computer or lab top or 'analogue computer' which is used to process analog data and etc.

• these days most ordinarily sort of pc that input data mistreatment separate instead of continuous, is named information processing system that use ‘binary digits’.

Generally following Computer hardware components are required:-

• Memory: it's a physical device (integrated circuits or chip) that permits a pc to store information and programs quickly or for good. It is also term as "primary storage". 

• Mass device (MSD): it's wont to store massive amounts of information for instance arduous disks, USB drive, CD-ROM etc. • Input device: it's any hardware device like keyboard and mouse that sends information to a pc. 

• Output device: it's a tool that sends information from a pc to a different device. 

• mainframe (Central process Unit): it's additionally said as a processor or brains of a pc that carries out the directions of a ADP system.

History of Computer:-
Professor Charles Babbage’s analytical engine thought-about as "fundamental framework of computer" could be a mechanical general programmable computing engine. It was a successor to the Difference Engine. Computer that we have a tendency to use nowadays is totally totally different from the primary generation laptop. Evolution in technology from nineteenth century to gift day changed laptop altogether. 
Uses of Computer:-
In digital world, from alittle gliding joint watch to house satellite all ar controlled by laptop. A small or massive machine was handled by humans in past, however in digitalized world these ar handled by programmed humans i.e. ‘Robots’. 
Types of Computer, 
By Size According to needed services speed or potency differing kinds of computers ar out there in market.

• Super Computer: Large in size and more powerful. Used for large and complex calculation.
• Mainframe Computer: Mainframe computers area unit smaller than mainframe. It has massive storage capability and capable to perform massive calculation. Used in bank, educational institution.
• Minicomputer: Minicomputers area unit multi user that area unit chiefly employed by tiny organization 
• PC: Microcomputer is outlined as tiny size, cheap, straightforward to hold pc e.g. Laptop, tablets.
