College of Engineering Operating Systems Assignment 1 - NIT1202

This document presents a comprehensive solution to an Operating Systems assignment (NIT1202). The solution begins with a review of a research article comparing smartphone operating systems, summarizing the article's key points, conclusion, and personal evaluation. The assignment then delves into memory management, demonstrating the best-fit and first-fit allocation algorithms. It explores the concepts of internal and external fragmentation. Further, it addresses page replacement algorithms (FIFO) and calculates success and failure ratios. The solution also covers processor scheduling algorithms, including FCFS, SJN, SRT, and Round Robin, analyzing turnaround times for different job sets. The document includes all necessary calculations, tables, and explanations to provide a thorough understanding of the concepts.
