The kernel is not a process—it’s a system. It serves user processes, reacts to context, and enforces isolation and control.

The kernel is not a process: It is the ever-present authority connecting hardware and software.
service of process: Manages syscalls, interrupts, and scheduling to keep user tasks running.
system of layers: Virtual, mapped, isolated, and controlled-structure at runtime.
