Binary Lesson 4 Hexadecimal and Binary Practice

Counting to 15 Base Base Base 16 Base Base Base 16 Two Ten (Hex) Two Ten (Hex) A A B B C C D D E E F F

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

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

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