[amp_mcq option1=”absolute mode” option2=”immediate mode” option3=”indirect mode” option4=”index mode E. None of the above” correct=”option1″]
The correct answer is A. absolute mode.
In absolute mode, the operand is given explicitly in the instruction. This means that the operand is a memory address, and the instruction will fetch the operand from that memory address.
B. immediate mode is a addressing mode in which the operand is encoded directly in the instruction. This means that the operand is not a memory address, but rather a value that is used by the instruction.
C. indirect mode is a addressing mode in which the operand is not a memory address, but rather a pointer to a memory address. This means that the instruction will fetch the operand from the memory address pointed to by the pointer.
D. index mode is a addressing mode in which the operand is a memory address that is modified by a register. This means that the instruction will fetch the operand from the memory address that is the sum of the memory address and the value of the register.
E. None of the above is not an addressing mode.
