LKM (Loadable Kernel Module)

A Loadable Kernel Module (LKM) is a piece of code that can be added to or removed from a computer's operating system kernel without needing to restart the system. Think of it as an upgrade or extension that enhances the kernel’s capabilities, like adding new features or drivers. LKMs allow systems to stay flexible and adaptable, enabling updates or new hardware support to be integrated seamlessly. This modular approach improves efficiency and maintainability by avoiding the need for complete system reboots when making changes.
