Addressing Modes: • Addressing mode provide different ways for access an address to given data to a processor • When 8086 executes an instruction, 

almost any instruction in the instruction set • Address is formed Direct addressing with a MOV instruction transfers data between a memory location, located within Addressing Modes of 8086 - I microprocessor operates in the real mode
