• • Hexadecimal is a number system thatis made up of 16 digits, 10 numbers (0-9) and 6 letters (A-F)
  • Each digit has a weight factor of 16 raised to a power, the right most digit is 1s (16^0),the next digit to the left 16s (16^1)

  
• • Hex is useful because large numbers can be represented using fewer digits.
  • It is beneficial to use hexadecimal over binary because:

  1. The more bits there are in a binary number, the harder it is to read
  2. Numbers with more bits are more prone to errors when being copied
