SCSI (Small Computer System Interface) is a parallel interface used by PC for harddisks, optical drives and several other devices. SCSI is derived from the SASI (Shugart Associates System Interface). Up to 8 devices can be connected on one interface including the host computer. Devices other than hard-disk needs a specific driver to work. A terminator is required at the end of the devices chain. There are two types of terminator, the passive and the active. The passive terminator simply connects the resistor to the bus line. The active terminator uses also an voltage regulator. Since SCSI-2, the use of an active terminator is mandatory.

More information about the standard can be found on Wikipedia.
