Summary of Addressing Modes

Answer:Implied Addressing Mode: The operand is implicitly defined by the instruction itself. For example, in "Complement Accumulator," the operand is understood to be the accumulator.Immediate Addressing Mode: The operand is explicitly stated in the instruction. For instance, "ADD 10" means to add 10 directly.Direct Addressing Mode: The address field contains the effective address of the operand. For example, "ADD X" directly uses the value at memory location X.Indirect Addressing Mode: The address field points to a memory location that contains the effective address of the operand, requiring two memory accesses.Register Addressing Mode: The operand is located in a CPU register, specified by the instruction.Indexed Addressing Mode: The effective address is calculated using a base address plus an offset, useful for accessing array elements.Auto-Increment/Decrement Modes: These modes automatically adjust the register address after accessing the operand, facilitating loop operations.
