A GigaByte is equivalent
to 1024
MegaBytes,
1,073,741,824 Bytes or 8,589,934,592 Bits
in
the basic form of digital information storage, being
composed of '0's or '1's in any combination.
On a CD or DVD the Bits are 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 had
disc the same principle to a CD applies, but the
pits and grooves are represented magnetically.
As a rough guide,
you can fit 4.7 GigaBytes of information on a full
size (12cm) DVD and 0.7 GigaBytes of information
on a standard (12cm) CD.
There are 8 Bits
in a Byte,
1024 Bytes in a Kilobyte (KB),
1024 KiloBytes in a MegaByte (MB),
1024 MegaBytes in a GigaByte (GB)
and 1024 GigaBytes in a TeraByte (TB).
