learning outcomes and competences to be acquired

Upon successful completion of this course, students will be able to demonstrate knowledge and understanding of:

  • the historical development of operating systems,

  • the various process states and context switching,

  • the benefits of using an operating system,

  • how applications interact with the operating system and each other

  • the major operating system modules (process management, deadlock, storage management, paging, caching, virtual memory, file system, protection and security),

  • the scheduling algorithms,

  • the filesystem operations,

  • the memory paging and segmentation,

  • the input/output mechanisms,

From the laboratory assignments, students will gain the abilities to:

  • fully utilize and program the Microsoft windows and Unix shell using scripts,

  • fully utilize the UNIX operating systems as a development platform for POSIX C,

  • use all the major POSIX system calls for designing single or multithreaded, host only or interconnected processes,

  • write programs that interface to the operating system at the system-call level,

  • use a variety of user level tools to monitor the behavior of operating systems.
