Learning Targets HL students I can outline OS resource management techniques: scheduling, policies, multitasking, virtual memory, paging, interrupt, polling. I can outline how an operating system hides the complexity of the hardware from users and applications. SL I can write a good IA section A I can write a good IA section B click here for guidance for your section A click here for guidance for your section B	Plan for our day HL students please break into groups and answer our question of the day Please restart your computer in verbose mode (hold down V key) please open console.log we will learn and practice reading a console we will learn and practice searching We will learn and practice looking at processes we will learn about process hierarchy parent / child we will visualize processes (activity monitor -> view -> all processes hierarchically) we will update frequency so you can see what your CPU is doing we will watch a video: 5 minute brain break! We will explore file i/o from your disk. sudo fssudo fs_usage -f filesys we now must memorize this table, putting it into our own words: Operating Systems management techniques SL students Please carefully follow these instructions and email me a link to your section A. Please look at the exemplar, which is very good. Please carefully follow these instructions and email me a link to your section B. If you are done, please ask a fellow student to look at your work, and assign a grade using the rubric on the above documents.
