Linux loadable kernel modules are loaded (and unloaded) by the modprobe command. They are located in /lib/modules and have the extension . ko (“kernel object”) since version 2.6 (previous versions used the extension .o). The lsmod command lists the loaded kernel modules.
How to check which modules are loaded in Linux?

What are Lib Modules?
The /lib directory contains kernel modules and shared library images (the C programming code library) needed to boot the system and execute commands in the root filesystem, ie. by binaries in /bin and /sbin. Libraries are easily identified by their filename extension *. then.
