Comprehensive practice problems covering OS fundamentals including CPU instructions, memory management, process management, threading, concurrency control, virtual memory, paging, and filesystem operations.
Introduces fundamental concepts of threads including thread creation, management, context switching, and thread design patterns. Explores differences between processes and threads, benefits of multithreading, and challenges in thread-based programming.
Adaptive Queue Management for Web Services
This paper explores adaptive queue management mechanisms for web servers under heavy load, presenting algorithms that respond to real-world traffic to improve fairness, responsiveness, and user quality of experience in overloaded environments.
Covers OS performance measurement techniques. Explains performance metrics (throughput, latency, utilization), measurement tools (profilers, benchmarks), workload characterization, bottleneck analysis, and techniques for improving system performance.
Introduces file systems and persistent storage. Covers file abstractions, directories, file operations (open, read, write, close), file descriptors, disk organization with tracks and sectors, and file allocation methods (contiguous, linked, indexed).
