You have this device (SMM BIOS), so ``udev`` loaded this module.

It creates `` /sys/class/hwmon/hwmon..`` for hardware monitoring.
Remove this module, and this file will disappear.

Do you need this file? We do not know, it is up to you to decide if you
want to monitor the fan and temperature of your laptop or not

I don't think it will make a real difference unless you have 16MB of RAM

Yes.

Almost any code that runs in kernel module may be installed as module:
there are netfilter modules, hardware drivers, bpf filter etc

Use ``modprobe``: it loads module dependencies

They are in
/lib/modules/$(uname -r)

"remove" module means unload it from the memory, not remove it from the disk
