  1. hexadecimal uses base 16 while decimal uses base 10. Hex counts from 0 to F. Each hex digit represents more information than a decimal digit and therefore large numbers take less space.
    It also fits nicely with the internal representation of data in a computer (based on multiples of 8-bit bytes).

  2. Extra digits are A, B, C, D, E and F to represent decimal values from 10 to 15.

  3. case does not matter.

  4. 34 = 0x22 (16*2 + 2)

  1. Hexadecimal numerals differ from decimal numerals by way of having six additional integers expressed by the letters: A, B, C, D, E and F. Though these symbols are expressed as letters, they now have a numerical value. This concept requires no longer thinking of these symbols as members of the alphabet, alone—they are now numeric representations of numbers in their own right.

  2. The extra “digits” in hexadecimal: A, B, C, E and F.

  3. Although there is a difference in appearance or style, there is no difference in value between uppercase and lowercase expressions of hexadecimal value.

  4. 34 decimal = 22 hexadecimal
