Lecture
This lecture introduces the concept of processes in operating systems, comparing them to the execution of recipes in a kitchen. It covers the analogy between the OS and a kitchen, the role of an operating system in managing resources, and the three main hats an OS wears. The lecture explains the creation of processes, their memory layout, and the process state transitions. It delves into CPU and memory virtualization, process APIs, and the execution of new programs using fork() and exec(). The lecture concludes with a case study on how a shell works and a summary of key concepts related to processes.
