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:
“O Captain! my Captain! our fearful trip is done,
The ship has weatherd every rack, the prize we sought is won,
The port is near, the bells I hear, the people all exulting,
While follow eyes the steady keel, the vessel grim and daring;
But O heart! heart! heart!
O the bleeding drops of red,
Where on the deck my Captain lies,
Fallen cold and dead.”
—Walt Whitman (18191892)
“There isnt a Parallel of Latitude but thinks it would have been the Equator if it had had its rights.”
—Mark Twain [Samuel Langhorne Clemens] (18351910)
