INPUT,OUTPUT AND STORAGE DEVICE.

INPUT DEVICE:

In computing, an input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or otherinformation appliance. Input and output devices make up the hardware interface between a computer and a scanner or 6DOF controller.There are different types of input devices. Keyboard, mouse, scanner, light pen and barcode reader and card reader are the examples. All input devices are connected with the CPU. Different signals are generated from these devices which are then sent to CPU.

OUTPUT DEVICE:

An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) to the outside world.Output devices are used to show the output of data. The data may be in the form of printouts, audio, video or an action. E.g. Printer, Speaker, Monitor and others.

STORAGE DEVICE:

A storage device is a hardware device capable of storing information. There are two storage devices used in computers; a primary storage device such as computer RAM and a secondary storage device such as a computer hard disk drive.Storage devices are used to store the data. Hard Disk is the most popular storage devices. Data once stored can be retrieved quickly and easily from these devices. Floppy Disk, Tape Drives and Flash drives are the examples of such devices.
