I have read the Operating System Concepts book, watched a lot of videos on YouTube, practiced with past qualifying exam questions and several exams from other CS departments around the world.

Although I feel better about going into the exam, I have been searching for:

  • Large diagram that puts most of OS concepts in perspective
  • Video that shows the lifecycle of a process, etc…

I can undersand full-well why such a digram may not exist. It is possible to propose a case of a concept then diagram its "life-cycle"... but I havent found one. Has anyone see anything like this? I am a very visual person and things make more sense to me when I can express them in a diagram.

At this point I feel that I will draw the diagram myself, and this way I can test my knowledge and also share it with others. But before I do that, I want to make sure I am not re-inventing the wheel.

If you are going to down-vote my question, please leave a comment also.

    $\begingroup$ I'm not sure what you are asking for. There's a ton of state diagrams showing the "lifecycle" of a process. Like technologyuk.net/computing/operating_systems/images/… or (more detailed) web.cs.mun.ca/~paul/cs3725/material/web/notes/img85.gif. But presumably you are asking for something more than that? What? $\endgroup$ – Wandering Logic Oct 24 '14 at 18:07

    $\begingroup$ I don't see any requests for opinions here, so I don't understand why people are voting to close as "primarily opinion-based". $\endgroup$ – David Richerby Oct 24 '14 at 20:42
  • $\begingroup$ It's not clear what the question is asking for. Without more specific guidance, selecting/designing such a diagram seems likely to be opinion-based, in terms of what concepts are included/emphasized and which ones are de-emphasized, what relationships are emphasized, etc. Imagine if we had 3 candidate diagrams -- I'm not seeing clear criteria articulated in the question that could be used to select between those candidates. $\endgroup$ – D.W.
