Which SCSI ID has a higher priority in a system, ID 0 or ID 7?

I am preparing for an exam and in one of my training exercises it says that the highest priority is 0, but in another exercise it says that the highest priority is 7. So I am very confused.

I don't really know but...

7 is the controller's SCSI address usually. I'd assume that it had priority.

The way I understand it.
0-7 id the highest number has priority but 8-16 lowest has priority. So it would be as following in lowest to highest priority

SCSI Arbitration Priority

by Bruce Epper In reply to SCSI ID's

For narrow SCSI, the priority is 0 (lowest) to 7 (highest). With wide SCSI, 8-15 are added below 0-7 with the higher number still being the higher priority. So the final result would be (from lowest to highest): 8,9,10,11,12,13,14,15,0,1,2,3,4,5,6,7
