System V Init

System V Init is the traditional system used by many UNIX and Linux systems to start, manage, and shut down the computer's services and processes during boot-up and shutdown. It relies on a set of scripts and runlevels to control which programs run at different states, like network startup or user login. Think of it as a conductor guiding various tasks in a specific order to ensure the system is ready for use. While newer systems are shifting to different methods, System V Init was a foundational way to organize and manage system initialization efficiently.
