Operating Systems
Operating Systems. Instructor: Prof. Sorav Bansal, Department of Computer Science, IIT Delhi. The course will provide an introduction to Operating Systems (OS), their design and implementation. We will discuss the goals of an OS, and some successful and not-so-successful OS designs. We will also discuss the following OS services in detail: thread scheduling, security, virtual memory, file system. We will understand the OS concepts practically by directly studying the source code of a small but realistic OS.
