how to edit a module installed

Hi friends,

I know insmod is used to install a module. But what if we want to replace
the module. Can anyone tell me the command to do that? 

rmmod is used to remove the module, but if you say the command for
replacing a module, it would be helpful.

'insmod' is a command to insert a module from your file system into the
running kernel. "rmmod" removes this loaded module from your running
kernel.

What do you mean with "replace the module"? On your file system?
