Computer Science & Systems Programming | Course Code: University Of California - Berkeley
- CS 162 | 2024-2025 Comprehensive Edition
📘 WHAT’S INSIDE THIS GUIDE:
✔ Kernel Execution Models: Dual-mode operation, Interrupts, System Call context switching, and
PCB/TCB states
✔ Concurrency Synchronization Primitives: Mutex, Counting Semaphores, and Mesa Condition
Variables with invariant loops
✔ Classic Concurrency Problems: Full Python reference code for Bounded Buffer, Readers-
Writers, and Dining Philosophers
✔ Deadlock Theory: Coffman's 4 Conditions, Resource Allocation Graphs, and step-by-step trace
of Banker's Safety Algorithm
✔ CPU Scheduling Algorithms: Step-by-step Gantt chart calculations of Average Turnaround and
Waiting Times across FCFS, SJF, and Round Robin
✔ Virtual Memory Page Replacement: Comprehensive step-by-step trace comparing FIFO
(Belady's Anomaly), LRU, and the Clock algorithm
✔ 10 Deadly Operating Systems Exam Traps flagged by professors (Mesa while loops, spinlock
uniprocessor hazards, hard vs. soft links)
