===Hex to Binary Conversion===
These words are shown in hexadecimal (the 0x denotes a hex number), so first they are broken down into 32bit binary words. First off, a word is just a number for the computer, which means this will just be converting a number from one base to another. Hexadecimal numbers have sixteen different digits, which range from 0 to F. Binary numbers only have two digits, which are 0 and 1. Because sixteen is a power of two (specifically 2^4), so a hex number can be written as a four digit binary number. The chart shows the conversion from hex to binary and decimal.

====Example====
Here is an example of how to break a hex word down to bits. The given hex word is:

0xfa8004081

The ‘0x’ just denotes that it is a hex word, so we ignore it for conversion. Following the chart, f becomes 1111, 8 becomes 1000, 0 becomes 0000, etc… When you put them all together our final binary word becomes:

11111000000000000100000010000001
