The Memory Address Register (MAR) holds the address of the current instruction or data that is to be fetched from or transferred to memory.
CloseFirst, evaluate each part of the expression separately:
The NOR operation returns true only if both operands are false. Therefore, false NOR true is false (0).
The value of the expression is 0.

First, evaluate each part of the expression separately:
The XOR (exclusive OR) operation returns true if exactly one of the operands is true. Therefore, false XOR false is false (0).
The value of the expression is 0.
