Introduction to Operating Systems | IIT Madras - #12 Introduction to Processes | Introduction to Operating Systems

Welcome to 'Introduction to Operating Systems' course ! This lecture focuses on the fundamental concept of processes in operating systems. The lecture begins by explaining how a process, such as printing "Hello World," interacts with memory and utilizes virtual addressing. It then describes the virtual address space of a process, dividing it into user and kernel space. The lecture further explores how the kernel space is mapped into the virtual address space of each process, highlighting the concept of a single kernel shared among all processes. Finally, the lecture introduces the Process Control Block (PCB) and its key elements, including process ID (PID) and process state.
