Parallel Port

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.

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 (1889–1945)

    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 mother’s death.
    Wallace Stevens (1879–1955)
