| STA | SCSI Trade Association. A group of companies that cooperate to |
| promote SCSI parallel interface technology as a viable mainstream I/O |
| interconnect for commercial computing. |
One of the ways data is transferred over the SCSI bus. Transfers are clocked with fixed frequency pulses. This is faster than asynchronous data transfer. Synchronous data transfers are negotiated between the SCSI host adapter and each SCSI device.

| Ultra SCSI | A standard for SCSI data transfers. It allows a transfer rate of up to |
| 20 Mbytes/s over an |
| SCSI bus. SCSI Trade Association (STA) supports using the term “Ultra |
