CA216 - Operating Systems

Quickest way to find this web page:
Google ca216 dcu
Think about it: All other ways (starting at the CA site, Googling my name, etc.) will take much longer to get here.
Just Google module code and DCU and it is the first hit.

About the notes


My notes contain many hyperlinks to background material. Some students get confused about what is the core course. The core course is anything that is linked to directly on this front page. All other links are just background material.




Notes

There will not be any talks in the labs.
In the labs, I will set you tasks to do, either for marks or for practice.
Tutors and I will be available to help.

Reading




Library categories




Wikipedia

Sometimes I link to Wikipedia. I need to write something in defence of this.

On the one hand, Wikipedia is deeply flawed, so you should use all links to Wikipedia with extreme caution. Many people refuse to link to it.

On the other hand, it is often clearly the best thing to link to on a topic. I say: Link to it, but use with caution and scepticism.
