CS 9252 OPERATING SYSTEMS syllabus and question papers

AIM:
The course introduces the students to the basic principles of operating systems.

OBJECTIVES:
  To be aware of the evolution of operating systems
  To learn what processes are, how processes communicate, how process synchronization is done and how to manage processes
  To have an understanding of the main memory and secondary memory management techniques.
  To understand the I/O Subsystem
  To have an exposure to Linux and Windows 2000 operating systems
