The magic of the page fault: understanding demand paging of virtual memory in linux

[@connorheadden3597]

Excellent video, I feel much better on the topic. Audiovisual feedback: For blocks of time during the presentation, the only movement the viewers eye can trace - is your movement in the bottom right of the screen. Therefore, the audience spends most of the time straining its eyes to see the thumbnail of you speaking. Suggested solutions: 1. Use more screen tools to speak to keep the audience looking at the screen more 2. If (1) is not possible, consider swapping screen sizes in presentation such that your image becomes a bit larger when only you are speaking and no movement is happening on the whiteboard. Thanks!

Thank you for sharing your knowledge, very informative videos. just a clarification, process memory does not start at 0? this is like reserved for issues like null pointers, correct?

[@kartarsingh7776]

I think null pointers are just specific to a language, not a process. You could have a language where there is nothing like a null pointer. Maybe for C++ they don't request to allocate the Page 0, so that no body can dereference that pointer, in case anybody tries to dereference the nullptr, there will be a page fault.

Too much of talking and not a clear explanation.
