Computer Instructions: Types of Operands (Address Modes)

Example: Suppose main memory and the CPU registers contain the following data:

RAM Address	Content
$100$	$200$
$200$	$400$
$300$	$100$
$400$	$300$
$500$	$1000$
$600$	$700$

CPU Registers	Content
$100$	$500$
IND	$500$
BASE	$300$

and that the stack contains the number $600$ on its top.

On the next slide, we'll explain what number the instruction LOD 100 will load into the accumulator AC.
