parallel port - Free On-line Dictionary of Computing (26 May 2007) :

  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.
