Next: The BIOS looks for the operating system (e.g. The Windows OS in the hard disk) and run it.

How data is stored on magnetic media?
Magnetic storage stores data with magnetic particles on the surface
1. Before data is stored, particles on the surface
are scattered in random patterns.
2. When storing data, the drive's read/write head
magnetizes the particles, and lead them in a positive or
negative direction ( 0 or 1).
