Discussion
In the Binary numbering system, a (1) represents a jumper being shorted and a (0) represents a jumper being open. On a three-bit jumper block on a SCSI drive, how would an ID of logical 3 be set?
Answer: C
Correct answer: 011
Three jumpers give three bits, and 3 in binary is 011:
\[ 0\times 4 + 1\times 2 + 1\times 1 = 3 \]
So the two low jumpers are shorted and the high one left open.
