Description

This course teaches the students standard operating systems structures. The students are exposed to topics such as concurrency and real-time considerations. The course discusses how common operating systems such as Unix and Windows are designed and implemented. This course spans the following topics: processes, threads, inter-process communication, synchronization (critical regions, semaphores, mutex, deadlocks), scheduling, memory management, i/o systems, and file systems.This course covers the following topics in detail: Operating system definition, simple batch systems, multiprogramming, time-sharing, personal computer systems, parallel systems, introduction to process, process scheduling, operations on processes, cooperating processes, interprocess communications, interrupts, process synchronization, critical-section problem, atomic instructions, semaphores, synchronization problems, CPU scheduling, scheduling criteria and algorithms, multiple processes and real-time scheduling, algorithm evaluation, deadlocks, characterization and handling of deadlocks, deadlock prevention avoidance and detection, deadlock recovery, memory management and virtual memory, address spaces, swapping, memory allocation, paging, segmentation.After completing this course, the studentBe able to explain what an operating system and the role is it different parts of the system play.Be able to explain the structure of operating systems, applications, and the relationship between them.Be able to explain and make use of the services provided by operating systemsExposure to details of major OS conceptsWrite programs (Implement) various parts of operating systems.
