Binary Math
Network devices communicate using BITS, where a bit is a single digit repre-
sented by a 1 or a 0, or by using BYTEs, where a byte is made up of eight bits in
any combination of 1’s or 0’s. A byte is also referred to as an octet.
Figure A-2
Bits and Bytes
An octet can be converted to or from binary using the technique shown in the
decimal conversion chart in Figure A-3. The conversion chart also shows the
decimal equivalent of the binary number.
Figure A-3 Binary to Decimal Conversion
Bits containing a 1 in Figure A-3 determine which decimal values should be
added. These decimal values, when added together, determine the decimal
equivalent for the binary number.
This is an example of changing a number expressed in binary (base 2) to its
decimal equivalent (base 10). The numeric value is the same, you have only
changed the numbering base (radix.) All digital processes are done in binary.
