 Digital data
consists of
discrete values
 Discrete values
can always
be mapped onto
integer (whole) numbers

Example:
 Discrete value set:
 {single,
married,
divorced,
widowed}

 Mapping (representation) to
integers:
0 = single
1 = married
2 = divorced
3 = widowed


 Integer (whole) numbers
in computer communication are
represented
using the Binary Number System:
0 > 00
1 > 01
2 > 10
3 > 11
