Prefix |
In telecommunications some very large and very small values are used. To make writing of these numbers easier use is made of a prefix. The prefix gives a value with which the value must be multiplied.
Some prefixes are also used in digital communications and computer technology but they have a slightly different value because they are based on a power of 2.
