A Bit is a binary
digit that forms the basic form of digital information
storage being either a 0 or a 1.
On a CD or DVD
the Bit is represented by 'pits' and 'grounds' (the
normal flat metallic surface of the disc without
any holes burnt or punched out of it) with a transition
between a pit and ground being a 1 and a continuous
spell within a pit or a ground being a 0.
On a tape or hard
disc the same principle to a CD applies, but the
pits and grooves are represented magnetically.
