Google and wikipedia are your friends ;)

http://en.wikipedia.org/wiki/Parallel_ATA#Parallel_ATA_interface

The parallel interface is being replaced by a serial interface but the
wikipedia page is still a good read, there are still lots of old
machines using only the parallel interface so it's good to know these
things.
