Usually, when one has a data bus for several parallel data lines at once, one refers to it as parallel. Serial - one data line, that sends bits sequentially. Parallel - several data lines, that send bits simultaneously. The most usual way of finding SCSI used with drives was as a parallel bus, anywhere from 25 to 50 pins per connector. -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.)
