3. Four Bits Make a Nybble 1 0 0 1 A nybble can be represented by one hexadecimal digit Values from 0 to 15, or 0 to F 8s 4s2s1s

4. Eight Bits Make a Byte 1 0 0 1 1 0 0 1 So this number is 128 + 16 + 8 + 1 = 153 8s4s2s1s8s4s2s8s4s1s2s8s4s 16s32s 128s 64s16s32s64s16s32s One nybble: 0 through F One nybble: 0 through F

5. Two hexadecimal digits make a byte 1 0 0 1 1 0 0 1 So this number is $99 = 9*16 + 9 = 144+9 = 153 One nybble: 0 through F # of 16s One nybble: 0 through F # of 1s
