it can store information. Formatting divides a disk into tracks
and sectors and creates addressable locations on it.
Graphics

monitor, printer, keyboard, or CPU.
Hexadecimal
A base 16 numbering system frequently used by programmers.
Any decimal number between 0 and 255 can be represented by
a two-digit hexadecimal number.

between equipment or programs.
