THE SPEAKERS
Speakers are one of the most common output devices used with computer systems. Some speakers are designed to work specifically with computers, while others can be hooked up to any type of sound system. Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener.
PRINTERS
A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to a A4 size paper.
computer printers can be renowned as impact or non-impact printers.
Color: Color is important for users who need to print pages for presentations or maps and other pages where color is part of the information. Color printers can also be set to print only in black-and-white. Color printers are more expensive to operate since they use two ink cartridges (one color and one black ink) that need to be replaced after a certain number of pages.
Memory: Most printers come with a small amount of memory (for example, one megabyte) that can be expanded by the user. Having more than the minimum amount of memory is helpful and faster when printing out pages with large images or tables with lines around them (which the printer treats as a large image).
PROJECTORS
Output devices that can take the display of a computer screen and project a large version of it onto a flat surface. Projectors are often used in meetings and presentations to help make sure everyone in the room can view the presentation.
