Addressing modes
Methods specifying where operand data comes from or results go, enabling flexible instruction design. Addressing modes include immediate, register, memory, indirect, indexed, and relative addressing.
Real World
When a program loops through an array of student grades, indexed addressing calculates each element's location by adding the loop counter to the array's base address, just like finding seat 5 in row B of an exam hall.
Exam Focus
Name the addressing mode, state where the operand comes from, and give a one-line use case — all three are needed for full marks.
