Computer Peripherals

Any device that is attached to the computer is considered a peripheral. Examples include the printer, monitor, and mouse. Information and commands are transferred from the computer to the peripheral device through controllers, which are often single chips. Controllers for items like the keyboard and disk drives are standard, while additional devices such as a modem usually require the insertion of new controllers from the expansion board. Furthermore, the bus (series of connected wires that connects peripherals with the computer) must be compatible with the controller. There are three basic types of bus architectures: the AT bus, PCI and SCSI. The links included herein relate to product reviews of various peripherals and related resources.
