The textbook for this course will be Operating Systems Concepts, 7th Edition, by Silbershatz, Galvin, and Gagne. It is a slightly newer edition that has lots in common with older editions; once I receive a copy I will see if older editions will work.

A highly recommended (though not required) book that will likely help with the projects will is:
Advanced Programming in the UNIX Environment (2nd Edition), by Stevens and Rago. This is just a good book to have if you ever do any Unix or Linux development.

Description and Grading

  • Description:
    This course studies the software systems that provide the interface between the computer system hardware resources and the users of the system. This interface is composed of a large collection of programs that provide simplified and uniform access to information storage (data and programs on tape, disk, and in memory), processing elements (CPUs and remote computers), input/output devices (telecommunications, keyboards, mice, video displays, printers, etc.), and data acquisition and equipment control devices. Topics include, processes and threads of execution, concurrent process synchronization, concurrent access to hardware resources, file systems, memory management and virtual memory, job scheduling, system modeling and performance evaluation, network communication and protocols, and computer and network security. A variety of example operating systems of different types will be examined and their characteristics compared. Prerequisites: COSC 175 and 251.
