Welcome to 'Introduction to Operating Systems' course ! This lecture focuses on CPU context switching, a mechanism that allows multiple processes to share a single CPU. It explains how the operating system utilizes a scheduler to allocate CPU time to different processes, creating the illusion of concurrent execution. The lecture then delves into the mechanics of context switching, describing the saving and restoration of process metadata, including the process control block (PCB), page tables, and kernel stack. It discusses the role of timer interrupts in triggering context switches and explains the concept of context switch overheads, including the time required to save and restore process states and reload the Translation Lookaside Buffer (TLB).
