+c) Material in Chapter 10 "File-System Interface" and Chapter 11 "File-System Implementation" of the book “Operating System Concepts”, 8th Ed;
+d) Material in Chapter 12 of the book “Understanding the Linux Kernel”, 3rd Edition related to the material in the slides listed in item b above.

+MAKE SURE YOU READ AND UNDERSTAND ALL THE MATERIAL IN THE SLIDES.
+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”.

+MAKE SURE YOU READ AND UNDERSTAND ALL THE MATERIAL IN THE SLIDES. PLEASE NOTE THAT ALTHOUGH THE EMPHASIS OF TEST 2 WILL BE ON MATERIAL THAT HAS NOT BEEN TESTED SO FAR, THE MATERIAL IN TEST 2 MAY STILL DEPEND ON KNOWLEDGE OF PREVIOUS MATERIAL.
