The octal numeral system is the base-8 number system, and uses the digits 0 to 7.
Octal numerals can be made from binary numerals by grouping consecutive digits into groups of three (starting from the right). For example, the binary representation for decimal 74 is 1001010, which groups into 1 001 010 — so the octal representation is 112. see more detailes at http://en.wikipedia.org/wiki/Octal
In computer technology and networking, an octet is a group of 8 bits. see http://en.wikipedia.org/wiki/Octet_%28computing%29
