board in processing equipment. It usually contains integrated
circuits that perform the processor’s basic functions and provides
connectors for adding other boards that perform special functions.
Sometimes called a main board.
MPEG:
Moving picture coding expert group is an industry standard
architecture for compression of video signals.
N
non-system disk:
A formatted diskette (floppy disk) you can use to store
programs and data but you cannot use to start the computer.
See
system disk.
nonvolatile memory:
Memory, usually read-only (ROM), that is capable of
permanently storing information. Turning the computer’s power off
does not alter data stored in nonvolatile memory.
numeric keypad overlay:
A feature that allows you to use certain keys on
the keyboard to perform numeric entry, or to control cursor and page
movement.
O
OCR:
Optical Character Recognition (reader). A technique or device that
uses laser or visible light to identify characters and input them into a
storage device.
OCR wand:
A device that reads, using an optical device, hand written or
machine printed symbols into a computer.
See also
OCR.
on-line state:
A functional state of a peripheral device when it is ready to
receive or transmit data.
operating system:
A group of programs that controls the basic operation
of a computer. Operating system functions include interpreting
programs, creating data files, and controlling the transmission and
receipt (input/output) of data to and from memory and peripheral
devices.
output:
The results of a computer operation. Output commonly indicates
data 1) printed on paper, 2) displayed at a terminal, 3) sent through
the serial port of internal modem, or 4) stored on some magnetic
media.
P
parallel:
Refers to two or more processes or events that can occur
simultaneously, and without interfering with each other.
See also
serial.
parallel interface:
Refers to a type of information exchange that transmits
information one byte (8 bits) at a time.
