(a) The word BUS has the denary values: B S 66 85 83 Convert the denary values into 8-bit binary. 66 H 85 83 [3] (b) Each letter in ASCII can also be represented as a hexadecimal value. The word KEY has the 8-bit binary values: E Y 01001011 01000101 01011001 Convert the three 8-bit binary values into hexadecimal. (0) 01001011 01000101 [3] 01011001
