1. The transfer clock for a SCSI bus is 20 MHz. Which is the transfer rate for a 16-bit data bus: (a) 10 MB/s (b) 20 MB/s (c) 40 MB/s (d) 80 MB/s
2. Explain the main differences between SCSI-I, SCSI-II and ultra SCSI. Outline their maximum data throughput, the connectors used and the size of their data busses. Also, outline some of the advantages of SCSI over busses such as the ISA bus.
3. State the SCSI lines that are used for simple error detection. Why is it not possible to detect which bits are in error?
4. Discuss the main system lines that are used in the SCSI bus and the operation of OR-tied driven signals.
