1. Course Description

This course aims to provide a broad introduction to modern operating systems for computer science and engineering. The course covers theoretical and practical challenges encountered when designing, implementing, and using operating systems. Topics include operating system structure, CPU scheduling, synchronization of concurrent processes, mutual exclusion, deadlock, main/virtual memory management

2. Course Main Objective

• To have detailed knowledge of various CPU-scheduling algorithms and process synchronizations.
• To gain knowledge of memory management and storage management.
• To master process coordination.

Consider the following set of processes, with the length of the CPU burst and Arrival Time are given in milliseconds: Process Burst Time Priority Arrival Time P1 P2 P3 1) CPU Scheduling implementation and evaluation Draw the Gantt chart that illustrate the execution of these processes using preemptive priority scheduling (a smaller priority number implies a higher priority). ................................. .. ...... .......................................... ........................................................................................... .... ....... ................................................................................ ....... 2) By analyzing the Gantt chart in question a), describe the waiting time for each process.
