MTL458: Operating Systems
Spring semester, 2020-21
Time of the class:
Mondays and Thursdays 9:30 to 10:50.
Office hours:
by email appointment.
Teaching assistants:
Priyamvada: maz178310@maths.iitd.ac.in
Abhay Saxena: mt6160648@maths.iitd.ac.in
Pavani: mt6160677@maths.iitd.ac.in
Syllabus:
The course, as the name suggests, will be about operating systems. It will broadly cover the following topics: operating system functions, basic concepts of abstraction, notion of a process, process execution, scheduling, memory management, multiprogramming, deadlocks, semaphores, file system, I/O devices and their management.
Course Material:
We will be following the book Operating Systems: Three Easy Pieces (OSTEP) for the most part, which is freely available online. I will be putting the links to the relevant chapters on this page after the lectures.
I might sometimes refer to some other material, in which case I will mention that. Students can also refer to these additional texts.
- Operating System Concepts (Wiley) by Silberschatz, Galvin, and Gagne
- Operating Systems | Internals and Design Principles (Pearson) by William Stallings
- Modern Operating Systems (Pearson)
by Tenanbaum
Credits:
Attendance of 75% is required to get credits for the course.
The course will be evaluated on a 100 point scale.
There will be 4-5 assignments, which will together make up 25 points.
The minor and major will be worth 30 and 45 points respectively.
To pass the course (i.e., to get a D grade), you need to have
at least 30 points.
To audit pass the course, you need to have at least 40 points, at least 15 of which have to come from the minor and at least 20 from the major.
Edit: Keeping in mind the pandemic, the audit pass criteria has been changed to be same as passing criteria for the course (for D grade). Also, the attendance requirement has been removed.
