Aims and Objectives
The course will start with a brief historical perspective of the
evolution of operating systems over the last fifty years, and then
cover the major components of most operating systems. This
discussion will cover the tradeoffs that can be made between
performance and functionality during the design and
implementation of an operating system. Particular emphasis will be
given to three major OS subsystems: process management
(processes, threads, CPU scheduling, synchronization, and
deadlock), memory management (segmentation, paging, swapping),
file systems, and operating system support for distributed systems.
