Operating Systems for MAANG Interviews

A book-shaped table of contents for operating systems at MAANG interview depth: foundations through processes, threads, concurrency, CPU scheduling, memory management, file systems, I/O, security & isolation, Linux internals, cloud/Kubernetes/observability, advanced kernel topics, and interview preparation — cross-linking existing sre/linux-networking, kubernetes-security, and patterns/concurrency notes instead of duplicating them.

1 — Process Fundamentals

Covers the process lifecycle, the process control block (PCB), process states, process context, the process image, and parent/child process relationships.

2 — Process Creation

Covers fork(), exec(), wait(), copy-on-write, zombie processes, orphan processes, and daemons.

4 — Interprocess Communication

Covers pipes, named pipes, shared memory, message queues, signals, sockets, RPC, and mmap().
