How anamosa101-coder/pbl works

This repository is a collection of OS-concept demonstrations and simulators, not one integrated application. Users run standalone IPC examples, operate a multi-process command simulator, or enter process data into a CPU scheduler; the web simulators cover deadlock and page replacement. The graph preserves those separate learning workflows and their domain stages. Some web and week-2 internals are represented by their exact enclosing directories because their source was not sampled; dashed links mark relationships not verified in excerpts.
