A computer system may consist of several devices. Every device has its own functionality. We need these devices to work properly with computer. We can divide these devices into following types.

Input devices: An input device is used to provide data to computer for processing or storing. 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 devices: 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 etc.

Storage devices: 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.
