Input device are used to put data and instructions into the computer. There are many different types of input device in other words an input device is a piece of computer hardware equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input device include keyboards, mouse, touch pad and joystick etc. Keyboard Computer Keyboard is a set of keys used to input text. Keyboard is found on computers like desktops and note books. Its layout is very similar to a typewriter. It is used for a wide range of tasks.

Computers use the binary system because it is easy to represent the two states 'on' and 'off' inside a computer. These two states are represented by voltages. 0 (Zero) volts is used to represent 0, and a voltage usually between 1 and 5 volts depending upon the types of computer, is used to represent 1. Computer uses different units to store data. A bit is a binary digit, the smallest increment of data on a computer. A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively. Because bits are so small, you rarely work with information one bit at a time. Bits are usually assembled into a group of eight to form a byte. A byte contains enough information to store a single ASCII character, like "h". A kilobyte (KB) is 1,024 bytes, not one thousand bytes as might be expected, because computers use binary (base two) math, instead of a decimal (base ten) system. Computer storage and memory is...

A computer is nothing but a combination of several non-living physical components. Whenever all those physical components [ called hardware ] in combination give an output then it is a computer. Let us take a look of the above picture of a computer. It consists of several hardware components like keyboard, Mouse, Speaker, Monitor, CPU, Hard Disk, Floppy, DVD/CD Rom etc. and the functions of all these parts are quite different. If you analyze all physical parts of a computer you will notice some devices are for inputting data, some for storing data, some are for processing and some for outputting. Naturally whatever is your computer system consists of ; they just perform the following four basic operations: Inputting => Storage => Processing => Outputting Inputting The process of entering data and instructions into the computer system. Inputting is done by the Input Devices. Examples of some input devices are: Keyboard, Mouse, Sound-cards, Video capture ca...
