Page Faults | The Backend Engineering Show

Hussein Nasser dives into page faults—what triggers them (first-access, stack growth, COW, swap, file-backed, permissions), why the kernel needs to handle them, and how virtual memory and VMA areas fit into the picture.

He timestamps every section (0:00–45:30), starting with OS fundamentals (VM abstraction, VMAs, kernel mode) and wrapping up with key takeaways, plus a handy list of his backend, Node.js, networking, and database courses for anyone wanting to dig deeper.
