* Most current operating systems and trends in software allow for large capacity disk access, but many setups still utilize ( physical / logical ) partitioning of the hard-drives. These are simply assignments of the divisioning of the hard-drive.
True / False

* The physical location of the heads of a hard-drive over a specific track location is identified as "_____________",  rather than tracks, because of multiple heads.
