Continuing to study for my A+ tests in a few weeks. I have ran into
another apparent discrepancy between the 2 sources I am using to study
from. Below is a question from the Total Recall material:

"What SCSI-2 feature enables a device to accept multiple instructions?

A. Parallel Porting
B. Dual Channel
C. Multi-tray Support
D. Command Queuing
E. Software Enbaled"

The correct answer is listed as dual channel.

In the Mike Meyers All-in-One Guide, here is what it says in the
section about SCSI-2:

"Part of the CCS included a new feature called command queuing that
enbaled a SCSI device to store multiple incoming commands."

Which is correct?
