In which directory structure are kernel modules typically found?

Kernel modules are typically found in the directory structure of /usr/lib. This directory serves as a standard location for libraries and is used by the kernel to manage modules that extend its functionality. Specifically, within /usr/lib, you will often find a subdirectory like /usr/lib/modules, which contains modules organized by kernel version. This allows the system to load various modules as needed for hardware support and other kernel functionalities.

The other directories mentioned serve different purposes. For instance, /bin is designated for essential user binaries and command-line utilities, while /etc is used for configuration files for the system and applications. The /usr/local directory is commonly employed for locally compiled software and libraries that are not part of the standard distribution, but it is not the designated location for kernel modules.
