Hard Disk

Is a piece of hardware that can be used for disk memory.

The surface area of a hard-disk is a disk divided into circular tracks which are then pie sliced into sectors (disk blocks). Tracks near the outer edge of the disk have more area than those closer to the spindle at the disk centre, so more slices are placed in them. Each sector generally has the same size (in Unix 1KB) and a unique address (disk block number).
