COSC4221 Test 1 will be held on Wednesday, October 17, 2012 19:00-21:00.

Test 1 will include:

a) Material covered in the lectures from the beginning of the term up to and including the lecture on Wednesday October 10;

b) Material in the files OSD.1.pdf, OSD.1.1.pdf, OSD.2.pdf, OSD.3.pdf, OSD.4.pdf, OSD.4.1.pdf in the course directory;

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.

(Please make sure that you have the most up-to-date version of the slides in the above mentioned files, as some of the slides may have been updated since you last downloaded them.)

It is possible that Test 1 may include true/false questions, questions that require short answers, questions that may require the drawing of diagrams, questions that require slightly longer answers, and other possible question formats.

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”.
