1) Single-Ended signaling
2) Differential Signaling
Ultra wide SCSI. wide SCSI buses support 16 devices, rather than the eight devices specified in regular SCSI.
Most modern SCSI buses support a total of 16 devices, while older SCSI implementations usually support only eight devices.
Depends on what the SCSI is. Ultra? Ultra Wide? Ultra Wide 2? many different types.
SCSI
SCSI or Small Computer System Interface is a set of standards for connecting computers and peripheral devices for data transfer. SCSI is commonly used for hard disks and tape drives, but can connect a wide range of other devices like optical drives like CD/DVD drive if the specific device being connected supports the standard. There are different SCSI port types like parallel SCSI, serial SCSI, Fiber SCSI and iSCSI. More details can also be found on Wikipedia. http://en.wikipedia.org/wiki/SCSI - Neeraj Sharma
