CMSC412 - Operating Systems

From CS 400 Level Course Wiki
Jump to: navigation, search
Specialization: Cybersecurity

Course Information
The operating system is always running and has complete power over the entire machine: it chooses which programs to run and when, how to organize files on a disk, which processes should get the most memory, and how different processes can communicate. Your task will be to implement pieces of an operating system including virtual memory, a file system, synchronization primitives (maybe), a device (maybe), fork and pipe (maybe). A bug can be catastrophic and elusive. In understanding how these features are built, you will be able to design code that better exploits the underlying hardware, write lightweight operating system features for embedded hardware, and sharpen your debugging skills.

Hours Per Week
10-20 hours. It's a four-credit class. The amount of time students spend on the assignments varies widely, and depends largely on their ability to write code that starts with not too many bugs and then the time to reason through any remaining errors.

Languages Used

Recommended Prior Experience
A B or better in 216, or experience in another C-based course (possibly 417) or heavy programming course. Concretely, a student should have no question on whether to use the & operator or the * operator when dealing with pointers and should understand the difference between sizeof() and strlen().

Projects, Exams, or other Assessments ~45% exams, ~35% projects, some quizzes, participation, etc. No group work outside class.

Misc Info
Qualified CS students do very well in 412; do not be intimidated by CE's.
