Virtual memory, paging and the TLB

Notes for offline study · 3 November 2026

Key points

  • Paging splits virtual memory into pages mapped to physical frames by a page table.
  • The TLB caches recent page-table entries so most translations skip memory.
  • A page fault occurs when the page is not in main memory and must be loaded.
