Day44: Master OS Fundamentals—Processes, Threads, PV, Deadlock, Memory & I/O

This tutorial walks through core operating‑system concepts—including resource management, user vs. kernel mode, processes and threads, state transitions, synchronization, PV (producer‑consumer) semantics, deadlock conditions and prevention, paging address translation, virtual memory, page‑replacement algorithms, file‑system allocation, and I/O models such as blocking, non‑blocking, multiplexing, and asynchronous I/O—using a regional medical imaging platform as a running example.
