Indexed addressing
Addressing mode computing address as base address plus index register offset. Indexed addressing enables efficient array traversal.
Formula
Effective Address = Base + (Index × Element Size)
Real World
When Netflix loads your watchlist, each title sits at a known offset from the list's start address — indexed addressing lets the CPU jump to item 7 by calculating base + 7 × item_size without scanning from the beginning.
Exam Focus
Link indexed addressing explicitly to array traversal — examiners expect you to explain why incrementing the index register accesses successive elements.
