In a terminal, type in LS space slash lib, slash modules, slash dollar sign, left parentheses, uname, space dash R, right parentheses, slash kernel, and hit enter. The dollar sign and parentheses around uname dash R will execute that command, and the result will be inserted in its place. This is an easy way of inserting the current kernel version into the path, without having to look it up. In this modules directory, we see other directories for drivers, filesystems, network and virtualization to name a few. To see the currently loaded modules, use the LSmod command.
