What is the transfer rate and bits supported by Ultra SCSI?

20 MB/sec and 8 bits
10 MB/sec and 16 bits
40 MB/sec and 16 bits
80 MB/sec and 16 bits

The correct answer is: 20 MB/sec and 8 bits

Ultra SCSI (Small Computer System Interface) supports a transfer rate of 20 MB/sec and uses 8 bits for data transfer. This might seem relatively slow compared to other options, but it has the advantage of being able to support longer cable lengths without experiencing signal degradation. Therefore, options B, C, and D, which offer higher transfer rates but also require more bits, are incorrect. It's important to note that although Ultra SCSI is considered relatively slow by today's standards, it was a significant improvement over its predecessors.
