How Virtual Memory and the Page-Fault Path works

An interactive concept flow for virtual memory and the page-fault path, from its assumptions through the main operation and boundary checks.

CONTRACTREPRESENTATIONOPERATIONBOUNDARYRESULT

readyVirtual memory lets each process use an address space that is translated through page tables and hardware translation caches. Pages provide the unit for mapping, protection, and often movement between RAM and storage. This abstraction supports isolation and flexible placement, but translations and misses have real costs.

Use the stages in order to explain virtual memory and the page-fault path. Each stage makes one assumption visible: what the operation promises, what representation it uses, how state changes, which boundary can invalidate a shortcut, and what evidence confirms the result.
