A Byte is a set
of 8 binary digits (Bits)
in the basic form of digital information storage,
being composed of '0's or '1's in any combination. For
example a byte look like '01101011'.
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.
