MAC Addresses are unique identification addresses to distinguish different devices operating on the same computer network. MAC addresses are composed of six hexadecimal numbers that range from 00 to FF (0 to 255 in decimal). As with all other pieces of electronic information, on a machine level MAC addresses are represented in binary strings made up of 0s and 1s. Binary representations are good for many things, but being easily readable by humans is not one. For that reason, MAC addresses are represented with hexadecimal numbers in order to increase rapid user comprehension and readability. Depending on certain software applications, the MAC address must still be handled in binary, and for that reason being able to easily translate one into binary code is a skill every person interested in computers should master.
