Kernelmoduuleita

Kernelmoduuleita, often referred to as kernel modules, are pieces of code that can be dynamically loaded into or unloaded from the Linux kernel at runtime. This allows for extending the functionality of the kernel without needing to recompile the entire kernel itself or reboot the system. They are a fundamental part of how the Linux kernel manages hardware and software.

Common uses for kernel modules include device drivers, filesystem support, network protocols, and other specialized functionalities. When a device is connected or a particular service is required, the kernel can load the corresponding module, making the necessary code available. Conversely, if a module is no longer needed, it can be unloaded to free up memory.

The process of managing kernel modules is typically handled by user-space utilities such as `insmod` for loading, `rmmod` for unloading, and `lsmod` for listing currently loaded modules. The `modprobe` command is a more advanced utility that can automatically load required modules and their dependencies. Kernel modules are typically stored as `.ko` files in specific directories within the filesystem. This modular design contributes significantly to the flexibility and adaptability of the Linux operating system, allowing it to support a vast array of hardware and software configurations.
