Principles

Processes and cores; scheduling, context switching and interrupts; concurrency and parallelism; OS services, startup and protection.

Application & programming

Use the mechanic-shop analogy and saved execution state to explain CPU sharing and process resumption.

Week 4 slides and reading are available above. Recordings are in preparation.

Learning focus

Explain ready, running and blocked states, CPU sharing, context switching and concurrency versus parallelism. Apply Week 3 control-flow knowledge in the branch-and-loop lab.

D: do independently · M: explain and modify a worked example · R: recognize, trace and compare.

Revisit: Predict register changes before running a loop.

Wednesday 14 Oct · Recitation

Branch and loop tracing; test cases that expose a wrong branch.

Start time tentatively 16:30; room to be announced.

Friday 16 Oct · CSE107

Lab 03: Assembly: branches & loops

Trace branches and loops, test a changed input and explain the outcome.

Attend your assigned two-hour group. Handout in preparation.
