CMOS Complimentary Metal-Oxide Semiconductor. A low-power silicon chip used for RAM and switching operations. CMOS is backed up by a battery. Controller A processor, interface, port, or adapter that translates data between the CPU and a peripheral device, such as a hard disk, diskette drive, keyboard, or video monitor. Controllers convert data from one format to another, match speeds between devices that operate at different speeds, and perform other functions. CPU Central Processing Unit. The primary device that interprets instructions, performs tasks, keeps track of stored data, and controls input and output operations. See also Processor. Device A piece of computer equipment that performs a specific task, such as a disk drive, a monitor, a printer, or a scanner. Also called a peripheral. Device driver A file containing instructions that allow your computer to recognize and communicate with a device. The device may be a printer, monitor, or other type of device. DIP Dual Inline Package. A type of chip that has two rows of downward-pointing pins. 2 Glossary

CMOS
Complimentary Metal-Oxide Semiconductor. A low-power
silicon chip used for RAM and switching operations. CMOS is
backed up by a battery.
Controller
A processor, interface, port, or adapter that translates data
between the CPU and a peripheral device, such as a hard disk,
diskette drive, keyboard, or video monitor. Controllers convert
data from one format to another, match speeds between
devices that operate at different speeds, and perform other
functions.
CPU
Central Processing Unit. The primary device that interprets
instructions, performs tasks, keeps track of stored data, and
controls input and output operations. See also
Processor.
Device
A piece of computer equipment that performs a specific task,
such as a disk drive, a monitor, a printer, or a scanner. Also
called a peripheral.
Device driver
A file containing instructions that allow your computer to
recognize and communicate with a device. The device may be a
printer, monitor, or other type of device.
DIP
Dual Inline Package. A type of chip that has two rows of
downward-pointing pins.
