In Linux, what describes sdb? (Choose all that apply.)
A. Refers to an IDE device
B. Refers to a SCSI device
C. Refers to USB device
D. Refers to FireWire device
B, C, and D. Linux will name and IDE device, normally, with had, hdb, hdc, or hdd, to denote their position on the ATA controller (primary master, primary slave, secondary master, secondary slave, respectively). SDB is the second SCSI device, and since Linux calls USB or FireWire devices SCSI devices, any of the three (B, C, or D) could be represented by sdb.
