What is the transfer rate and number of bits for Fast SCSI-2?

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

The correct answer is: 10 MB/sec and 8 bits

Fast SCSI-2 has a transfer rate of 10 MB/sec and uses 8 bits for data transmission. This is different from the other options because they either have a different transfer rate or use a different number of bits. For example, option B has a transfer rate of 20 MB/sec, which is double the correct answer, and uses 16 bits, which is double the number of bits used for Fast SCSI-2. Similarly, options C and D have lower and higher transfer rates respectively, and use either less or more bits for data transmission. Therefore, A is the only correct answer for the transfer rate and number of bits for Fast SCSI-2.
