  2. Four Bits Make a Nybble 4s 2s 1s 8s 1001 A nybble can be represented by one hexadecimal digit Values from 0 to 15, or 0 to F

  3. Counting to 15 Base Two Base Ten Base Two Base Ten 0 0 1000 8 1 1 1001 9 10 2 1010 10 11 3 1011 11 100 4 1100 12 101 5 1101 13 110 6 1110 14 111 7 1111 15

  4. Eight Bits Make a Byte 128s 64s 64s 32s 32s 32s 16s 16s 16s 8s 8s 8s 8s 4s 4s 4s 4s 2s 2s 2s 1s 1s One nybble: 0 through F One nybble: 0 through F 10011001 So this number is 128 + 16 + 8 + 1 = 153

  5. Two hexadecimal digits make a byte One nybble: 0 through F # of 16s One nybble: 0 through F # of 1s 10011001 So this number is $99 = 9*16 + 9 = 144+9 = 153
