Students are introduced to the structure of modern operating systems. Topics include virtual memory, resource allocation strategies, concurrency, and protection. The design and implementation of a simple operating system are performed.

CSE 219 or CSE 260; CSE 220 or ESE 380

• Introduce the fundamental concepts underlying modern operating systems, including virtual memory and multiprogramming.
• Provide students with a working knowledge of the components of operating systems, including file systems, the I/O subsystem, and the CPU scheduler.
• Give students experience designing and implementing simplified versions of the main modules of operating systems.
