Question

In the absolute addressing mode:

• A. The operand is inside the instruction
• B. The address of the operand is inside the instruction
• C. The location of the operand is implicit
• D. The register containing the address of the operand is specified

Hint:

In Absolute Addressing Mode: - The memory address of the operand is explicitly given in the instruction. - It provides direct access to memory but lacks flexibility compared to register and indirect addressing.

Answer 1

The Correct Option is B

Step 1: Understanding Absolute Addressing Mode
- Addressing modes define how an operand is accessed in an instruction.
- Absolute Addressing Mode is a mode where the instruction directly specifies the memory address of the operand.
Step 2: Characteristics of Absolute Addressing
- The operand is not inside the instruction, but its memory address is explicitly provided in the instruction.
- This allows direct access to a specific memory location.
- Example: \[ \text{MOV A, 2000H} \] Here, 2000H is the absolute address from which data is fetched.
Step 3: Evaluating the Options
- (A) Incorrect: The operand itself is not inside the instruction, only its address is.
- (B) Correct: The address of the operand is part of the instruction.
- (C) Incorrect: The operand location is explicit, not implicit.
- (D) Incorrect: No register is specified; the instruction directly provides the memory address.
