Chapter 5, Problem 1RETC

Explanation of Solution

data movement instructions:

data like bytes, words, or doublewords are moved from one place, called the source operand to another place, called the destination operand.

difference between register-to-register, register-to-memory, and memory-to-memory instructions:

Register-to-register	Register-to-memory	Memory-to-memory
Operands may not be in memory.	Atleast one operand must be in a register and one in memory.	Two or three operands may be present in memory
Move instructions move data from one register to another.	Store instructions move data from registers to memory	Move(MOV) may not work in this case however (MOVS) is used as string move instruction.
