Hexadecimal Conversion

Hexadecimal overview

Hexadecimal, also known as hex, is a numeral system with a base of 16, usually written using
unique symbols 0–9 and A–F, or a–f. Its primary purpose is to represent the binary code that
computers interpret in a format easier for humans to remember. It acts as a form of shorthand, in
which one hexadecimal digit takes the place of four binary bits. For example, the decimal numeral
79, with the binary representation of 01001111, is 4F (or 4f) in hexadecimal where 4 = 0100, and
F = 1111.
Hexadecimal numbers can have either an 0x prefix or an h suffix. The address 0xFFFFFA is the
same address as FFFFFAh.This type of address with 6 digits representing 3 bytes, is called a hex
triplet. Fibre Channel uses hexadecimal notation in hex triplets to specify well-known addresses
and port IDs.

1. Separate the 6 digits into triplets by inserting a space after every 2 digits: 61 06 00
2. Convert each hexadecimal value to a decimal representation:
