Portable Devices

Portable Devices and Peripherals

What does peripherals mean and what are the differences between portable devices?

Peripherals

Input:

An input device is any hardware device that sends data to the computer, without any input devices, a computer would only be a display device and not allow users to interact with it, much like a TV. (Example: Keyboard, mouse, USB, Games controller)

Output:

Computer output devices get information out of the computer, delivering data that has been processed by the computer to you, the user. Output devices produce data in different forms including audio, visual and hard copy. (Example: Printer, flash drive, speakers, monitor, games controller)

Storage

Optical Storage:

Optical storage devices save data as patterns of dots that can be read using light. A laser beam is the usual light source. (Example: CD, DVD).

Magnetic Storage:

Magnetic storage media and devices store data in the form of tiny magnetised dots. These dots are created, read and erased using magnetic fields created by very tiny electromagnets (Example: Floppy disk)

Solid State:

The term ‘solid-state’ essentially means ‘no moving parts’. Solid-state storage devices are based on electronic circuits with no moving parts (no reels of tape, no spinning discs, no laser beams, etc.)
