[amp_mcq option1=”Absolute mode” option2=”Indirect mode” option3=”Immediate mode” option4=”Index mode E. None of the above” correct=”option4″]
The correct answer is D. Index mode.
In index mode, the effective address of the operand is generated by adding a constant value to the contents of a register. The constant value is called the index, and it is stored in a register called the index register. The effective address is calculated by adding the index to the contents of the index register.
For example, if the index register contains the value 100 and the constant value is 20, then the effective address is 100 + 20 = 120.
Absolute mode is a addressing mode in which the effective address of the operand is stored in the instruction itself.
Indirect mode is a addressing mode in which the effective address of the operand is stored in a memory location.
Immediate mode is a addressing mode in which the operand is stored in the instruction itself.
None of the above is not an addressing mode.
