Introduction & Definition of Computer

with No Comments

To elaborate the Definition of Computer first need to know the origin of the word computer. The ”Computer”, word came from Latin word “Compute”. Computer is an electro mechanical device which can accept data from external sources, process through them in CPU & the processed data give us through output device. Computer accepts data, we known as this device is Input device. Like as- Key Board, Mouse, DVD ROM, scanner, Joysticks, Touch Screen, Voice Input, Audio Input, WEB Cams, Digital Camera etc. Computer gives result or processed data, we known as these devices are output device. Like as- Monitor, Sound box, Printer, Video Card, Dot-Matrix, etc.

Storage Devices:

We can store data, information and instruction for the use in future. The example of storage devices are- Floppy Disk, Hard Disk, External Hard Disk, Smart Card, Pen Drive, Cloud Storage, CD-ROM, DVD-ROM etc.

The route of computer is “Abacus”.

Abacus:- It is a first counting device in  the world or one type of calculation method. This process first used by Chinese before five thousand years ago. The same type of device used by Japan, it was called ” Saroyan “.

Charles Babbage“ is known as the father of computer.
