Detailed explanation-1: -Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are defined in a given instruction set architecture define how the machine language instructions in that architecture identify the operand(s) of each instruction.
Detailed explanation-2: -Indexed addressing mode is used to access elements in arrays which are stored in memory at consecutive locations. This addressing mode will allow the program to access a location by incrementing or decrementing the index value.
Detailed explanation-3: -Explanation: Absolute mode: In this addressing mode, the address of location of the operand is given explicitly as a part of the instruction. This addressing mode is also known as direct addressing mode.
Detailed explanation-4: -Register Direct Addressing Mode-The address field of the instruction refers to a CPU register that contains the operand. No reference to memory is required to fetch the operand.
