Problem:
a) Explain types of "Addressing Modes".
b) What is the difference between "Rotate" and "Swap" Operations?
c) A computer spends a lot of time in moving data from one location to another, using four addressing modes. Write the mnemonics and the operations of putting the number 34h in registers R5, R6, and R7. Use two different methods for this problem.
