A device that feeds data into a computer, such as a keyboard or mouse, is called an input device. Output: Anything that comes out of a computer. Output can be meaningful information or gibberish, and it can appear in a variety of forms -as binary numbers, as characters, as pictures, and as printed pages. Output devices include display screens, loudspeakers, and printers.

Optical Storage

Optical storage is any storage method in which data is written and read with a laser for archival or backup purposes. Typically, data is written to optical media, such as CDs and DVDs. For several years, proponents have spoken of optical storage as a near-future replacement for both hard drives in personal computers and tape backup in mass storage.

Magnetic Storage

A device utilizing magnetic properties of materials to store data; may be roughly divided into two categories, moving (drum, disk, tape) and static (core, thin film). This is also known as magnetic memory. 

Solid State

Solid state, at its most basic level, means "no moving parts." Therefore, solid state electronic devices are made up of solid components that do not move. Some examples include computer motherboards and integrated circuits. Devices that use only solid state parts, such as television sets, speakers, and digital watches, are often referred to as solid state products.
