OUTPUT DEVICES
Description of purpose: The purpose of the printer is to produce hard copies of documents, files and pictures sent by command to the computer; it produces documents in hard copy stored in electrical form. Printers are mainly attached by cables, some printers typically known as network printers have built in network interfaces (wireless/Ethernet) and can serve as a hard copy device
How it communicates with other components: Modern printers can directly interface with electronic media such as memory sticks or memory cards and to capture devices, some printers are combined with fax machines/photocopiers and these are mainly known as multi function printers
In other words: The printer is used to produce hard copies or documents sent by
command to the computer, and produces it in hard copy form, as opposed to a
scanner which converts hard copies into electronic copies

Description of purpose The computer speakers are an output device which provides auditory feedback to the user, they may be built into the system unit or connected with cables, the speakers allow you to listen to music and hear sound effects from your computer. There are different types of speakers depending on the kind of application you use, depending on how much clarity you want digital speakers provide much more definition and usually such clarity is involved in surround sound speakers.
How it communicates with other componentsIn speakers, sound travels in air waves and we hear sounds differently depending on the frequency and amplitude of these waves, the diaphragm of the speaker mainly made of paper, plastic or metal is attached to the suspension which produces surround sound by rapidly vibrating a flexible cone. The narrow end of the cone is connected to the voice coil

Description of purpose The purpose of the computer monitor is to serve the visual display of text and graphics to help the user navigate through the computer through files, applications, documents. The monitor is a way a computer can be communicated with the user
How it communicates with other components
The most frequently used output device on a computer, the display provides instant feedback by showing you text and graphic images as you use the computer, most desktop displays use liquid crystal display (LCD) or cathode ray tube (CRT)
