 ALSO NOTE THAT DRAWING THE SAME KIND OF DIAGRAMS AS ILLUSTRATED IN THE SLIDES, WILL BE AN IMPORTANT COMPONENT OF TEST 1. For example, if you are given a diagram similar to that on slide 9 of OSD4.pdf, “Example of a Small File System Tree in Unix”, then you should be able to draw the corresponding diagram on slide 10, “Internal Structure of Small File system Tree in Unix”, as well as the corresponding diagram on slide 24, “In Memory VFS Objects and On Disk Objects”.

 Also please note that, unfortunately, I am unable to provide individual answers to individual student questions regarding what kind of questions may be included, or not included, in the tests, beyond what I had said during the lectures and what has been posted on the course website above.
 The reason is because doing so will be unfair to other students in the class who do not receive the same information.
