LSI 20860 manual Single-Ended, Termination, Ultra Scsi

Single-Ended

SCSI

A hardware specification for connecting SCSI devices. It references each SCSI signal to a common ground. This is the most common method (as opposed to differential SCSI which uses a separate ground for each signal).

Termination	The electrical connection required at each end of the SCSI bus,
	composed of a set of resistors. It improves the integrity of bus signals.
Ultra SCSI	A standard for SCSI data transfers. It allows a data transfer rate of up to
	20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit
	SCSI bus. The SCSI Trade Association (STA) supports using the term
	“Ultra SCSI” over the term “Fast-20”.
