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 — Scheduling Fundamentals

Covers scheduling goals: throughput, turnaround time, waiting time, response time, and fairness.

2 — Scheduling Algorithms

Covers FCFS, SJF, SRTF, round robin, priority scheduling, multilevel queue scheduling, MLFQ, and lottery scheduling.

1 — What is an Operating System?

Covers the evolution of operating systems, the goals of an OS, types of operating systems, kernel vs. user space, monolithic vs. microkernel vs. hybrid kernels, system calls, and the boot process overview.
