Course Overview

Operating systems are central to computing activities. An operating system is a program that acts as an intermediary between a user of a computer and the computer hardware. Two primary aims of an operating systems are to manage resources (e.g. CPU time, memory) and to control users and software. Operating system design goals are often contradictory and vary depending of user, software, and hardware criteria. This course describes the fundamental concepts behind operating systems, and examines the ways that design goals can be achieved.

What are the requirements?

  • To undertake this course, you should have taken an undergraduate level course on, or be familiar with, basic hardware and software aspects of computer systems organization.

What am I going to get from this course?
