Section 11.2 Directories

File Organization and Pathing: https://www.youtube.com/watch?v=dpDRg--OuFA 4/5/15 Uploaded on: 2/5/12 This video overviews the topic of file organization and pathing, meaning it glosses over how different data files are kept and filtered throughout the operation system, as well as the different ways of pathing a user can use in order to find those files in that given system.

Windows vs. linux directory structure http://www.howtogeek.com/137096/6-ways-the-linux-file-system-is-different-from-the-windows-file-system/ This helped me better understand and learn how to navigate the two major directory/ file systems used. Joseph Clark

Section 11.3 Disk Scheduling

http://www.cs.iit.edu/~cs561/cs450/disksched/disksched.html This page gives all basic information of Disk Scheduling. added 04-03-15 Leon Ngo This website has more in depth descriptions for each type of algorithm. It also has better examples for each algorithm. Each example uses a number line and lines underneath to show how each algorithm is performed. added: 11/6/2015 Zachary Brogna

http://www.ijcsi.org/papers/IJCSI-11-1-1-74-79.pdf Date Added 11/7/15. Date Created 1/1/14. This link goes over the basics of different algorithms for disk scheduling. The types of algorithms that are talked about in this article are First Come First Served, Shortest Seek Time First, SCAN, C-SCAN, LOOK, and C-LOOK. The paper also gives an example problem with the explanation of each algorithm. ~Caitlyn Lambert-Hutchinson

http://www.ecs.umass.edu/ece/koren/architecture/Disk/help.htm This website helped me a lot because in each disk scheduling algorithm it took you step by step and then also a had an entire other simulation page. Date created: unknown Date added: 11-8-15 ~Rebecca Sherr
