Operating Systems Julian Bradfield
[email protected] IF{4.07 Course Aims I general understanding of structure of modern computers I purpose, structure and functions of operating systems I illustration of key OS aspects by example Course Outcomes By the end of the course you should be able to I describe the general architecture of computers I describe, contrast and compare differing structures for operating systems I understand and analyse theory and implementation of: processes, resource control (concurrency etc.), physical and virtual memory, scheduling, I/O and files In addition, during the practical exercise and associated self-study, you will: I become familiar (if not already) with the C language, gcc compiler, and Makefiles I understand the high-level structure of the Linux kernel both in concept and source code I acquire a detailed understanding of one aspect (the scheduler) of the Linux kernel Course Outline This outline is subject to modification during the course. I Introduction; history of computers; overview of OS (this lecture) I Computer architecture (high-level view); machines viewed at different abstraction levels I Basic OS functions and the historical development of OSes I Processes (1) I Processes (2) { threads and SMP I Scheduling (1) { cpu utilization and task scheduling I Concurrency (1) { mutual exclusion, synchronization I Concurrency (2) { deadlock, starvation, analysis of concurrency I Memory (1) { physical memory, early paging and segmentation techniques I Memory (2) { modern virtual memory concepts and techniques I I/O (1) { low level I/O functions I I/O (2) { high level I/O functions and filesystems I Case studies: one or both of: the Windows NT family; IBM's System/390 family { N.B.
