A parallel port is a type of interface found on computers (personal and otherwise) for connecting peripherals. In computing, a parallel port is a parallel communication physical interface. It is also known as a printer port or Centronics port. The IEEE 1284 standard defines the bi-directional version of the port, which allows the transmission and reception of data bits at the same time.

Some articles on parallel port:
... In early parallel ports the data lines were unidirectional (data out only) so it was not easily possible to feed data in to the computer ...
... Each board comes complete with all the cables between the board and computer parallel port (with sub-hoods) and terminates in a male DB-9 connector for interface into the radio ... needed because the MT8870 has latched outputs, and the IRLP software looks for short pulses at the parallel port pins 10,12,13,15 in order to acknowledge a DTMF digit ... HCF4081 (pins 3,4,10,11) connect to the parallel port and provide the pulsed input that IRLP needs ...
... Adapters which support high speed trace ports generally include several megabytes of trace buffer and provide high speed links (USB or Ethernet) to get that data to the host ... Personal computer parallel port adapters are simple and inexpensive, but they are relatively slow because they use the host CPU to change each bit ("bit banging") ... They have declined in usefulness because newer computers do not have parallel port hardware ...
... The PC parallel port function requires a special adaptor (PPA, Parallel Port Adaptor) and a DB25 Parallel Port cable that are sold separately ...
Famous quotes containing the words port and/or parallel:
“When we think back to our forefathers, with their sedentary lives of forest-chopping, railroad-building, fortune-founding, their fox-hunting and Indian taming, their prancing about in the mazurka and the polka, with their coattails flying and their bustles bouncing, to say nothing of their all-day sessions with the port and straight bourbon,... we must realize that we are a nation, not of neurasthenics, but of sissies and slow-motion sports.”
—Robert Benchley (18891945)
“If from the earth we came, it was an earth
That bore us as a part of all the things
It breeds and that was lewder than it is.
Our nature is her nature. Hence it comes,
Since by our nature we grow old, earth grows
The same. We parallel the mothers death.”
—Wallace Stevens (18791955)
