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.

2 — Process Creation

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

3 — Context Switching

Covers kernel mode vs. user mode, saving registers, scheduling context, context switch cost, and process switching.

4 — Interprocess Communication

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