On Disk
A disk is a storage medium which consists of a flat circular disk covered on both sides with a magnetic material. Data is held on a number of circular concentric tracks on the surface of the disk and is read or written rotating the disk past read/write heads.
Disks can be used to store up boot-up programs due to the following reasons:
1. Disks have large storage capacities and can be written or read more quickly the computer. This minimise the computer start-up time i.e. the Winchester disk contains a number of flat sealed airtight packs.
2. Disk storage medium is less expensive than Rom storage media. For example, the magnetic disks can store substantial data, say a number of programs or lengthy programs.
