The video introduces fundamental concepts of processes in Linux, explaining that a process is a program in execution. It covers the multi-user and multi-tasking nature of Linux, where each process gets a unique process identifier (PID). The video also explains parent and child processes, using examples to illustrate their relationships. It delves into PID 0, known as the swapper or scheduler, and PID 1, which is the init system or system D, highlighting their roles in the Linux kernel. The video concludes with a recap of these concepts.
