init system

An init system is the starting point of an operating system, responsible for launching and managing all the other programs and services when the computer turns on. Think of it as the system's conductor, ensuring everything runs in the correct order and at the right time. It initializes essential components like network connections, user interfaces, and background services, maintaining stability and coordination. Different systems use different init methods, like Systemd or SysVinit, but their core role remains to manage the startup process smoothly and keep the system running efficiently.
