Base Base Base 16 Base Base Base 16 Two Ten (Hex) Two Ten (Hex) A B C D E F 2

3. 1 0 0 1 Four Bits Make a Nybble 8s 4s 2s 1s
A nybble can be represented by one hexadecimal digit
Values from 0 to 15, or 0 to F 8s 4s 2s 1s

4. 1 0 0 1 1 0 0 1 Eight Bits Make a Byte 8s 8s 8s 8s 4s 4s 4s 4s 2s 2s
So this number is
= 153

One nybble:
0 through F
One nybble:
0 through F

5. Two hexadecimal digits make a byte
Left nybble = 9; right nybble = 9
So this number is 0x99 = 9* = = 153
One nybble:
0 through F
# of 16s
One nybble:
0 through F
# of 1s
