Bit CD (Compact Disk.)
A Bit is a ‘binary digit’ either, 0 or 1. It’s the smallest piece
of data a computer can handle. A computer can handle a thin circular disk capable of holding up to 800 MB of
data (there is however dual storage disks capable of
millions of bits in its normal working routine. To make
sense of this, Bits are usually grouped together in a byte, holding 4Gb of data). Compact disks come in several for-
