What is a KiloByte? (KB)


A KiloByte is equivalent to 8,192 Bits or 1024 Bytes 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 approximately 4,800,000 KiloBytes of information on a full size (12cm) DVD and 716,000 KiloBytes 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).
