parallel port
point of connection within a computer to that enables it to read and transfer large sections of information
Parallel port
A parallel port is a type of socket found on
personal computers for interfacing with various peripherals. It is also known as a printer port or
Centronics port. The
IEEE 1284 standard defines the bi-directional version of the port.For the most part, the
USB interface has replaced the Centronics-style parallel port. Some printers use an
ethernet connection instead, and —
as of 2006 — many lack a parallel port connection. On many modern computers, the parallel port is omitted for cost savings, and is considered to be a
legacy port. In laptops, access to a parallel port is still commonly available through
docking stations.

parallel port
Noun
1. an interface between a computer and a printer where the computer sends multiple bits of information to the printer simultaneously
(synonym) parallel interface
(hypernym) interface, port
parallel port
A
port through which two or more
data bits are passed simultaneously, such as all the bits of an 8-
bit byte, and that requires as many
input channels as the number of bits that are to be handled simultaneously. Contrast with
serial port. [
From Weik '89]
parallel port
<
hardware> An interface from a computer system where data is transferred in or out in parallel, that is, on more than one wire. A parallel port carries one
bit on each wire thus multiplying the transfer rate obtainable over a single wire. There will usually be some control signals on the port as well to say when data is ready to be sent or received.
The commonest kind of parallel port is a
printer port, e.g. a
Centronics port which transfers eight bits at a time. Disks are also connected via special parallel ports, e.g.
SCSI or
IDE.
