Display the loaded kernel modules
In order to prevent the kernel from becoming bloated, Linux does not include programs other than those that are minimally necessary for operation in the kernel, but allows them to be added or detached depending on the environment.
The things that can be added or detached in this way are called "modules," and typical ones include SCSI adapters, PC cards, and device drivers.
The command to display what modules are currently installed is the "lsmod" command.
You will need root privileges to execute this command.
