Learning objectives
- Explain Copy-on-Write and
fork's Efficiency in terms of translation, protection, and performance costs instead of memorizing isolated terms. - Reason from the abstraction down to concrete events such as TLB misses, page faults, fragmentation, or allocation behavior.
- Use
operating-system-concepts,ostepto support diagrams, experiments, and debugging when the mental model is still unstable.
Prerequisites
- Comfort with the process abstraction and address-space basics from module 01.

External enrichment
- Linux Kernel Documentation: Memory Management (
official_docs_companion) - Useful for connecting the learner model of virtual memory to real kernel memory-management subsystems. - man 2 mmap (
read_if_stuck) - Good when the learner needs one concrete API to connect virtual-memory ideas to real process behavior.
