This page serves as a reference for teaching/learning operating systems (OS). The material consists of video lectures, annotated slides used in the videos, practice problems with solutions, programming lab assignments, and additional reading material for reference.

The content is broadly divided into the following parts.

• Parts A,B,C,D (lectures 1-20) cover basic concepts of operating systems that are taught in a regular UG OS course in a CS curriculum. This material is mostly based off the excellent online textbook Operating Systems: Three Easy Pieces (OSTEP), with pointers to the relevant chapters of the textbook provided against each lecture. A brief video lecture introduces the concepts from the textbook, and students are strongly encouraged to read the book chapters (that are freely available online) for a more in-depth understanding of the concepts.
• Part X (lectures 21-32) contains an in-depth discussion of OS concepts using the xv6 operating system as an example. The xv6 teaching operating system comes with concise source code and a textbook/commentary, and is a great resource to understand fundamental concepts using a simple OS. Here are links to the PDF formatted xv6 source code and the accompanying xv6 book for the latest x86 version of xv6 that is used in the lectures.
• Part N (lectures 33-35) provides an overview of the networking subsystem in Linux, and some recent advances in the area of improving network I/O performance.

• Virtualization and Cloud Computing
• Design and Engineering of Computer Systems

• Dive into Systems, by Suzanne J. Matthews, Tia Newhall, and Kevin C. Webb.
• Computer Systems: A Programmer's Perspective, by Randal E. Bryant and David R. O'Hallaron.
