pictures are perfered - We like pictures, too. They help us understand, what you mean. Please post screenshots or the text of the exact message that you get. – user 99572 is fine Mar 7 '13 at 14:34
@user99572isfine I just what to know the difference between the kernel module and driver which are just terms I think. – 张 源 Mar 7 '13 at 14:48

In the easiest way I can think:

a module is a "piece of software", of any kind. it is a part of the main kernel, not a "user program". a driver is a "piece of software" of one specific kind: it is needed to communicate with hardware components.

a "driver" IS a kind of module.

Drivers are the firmware required by the OS to actively use the hardware on your system. Modules are like add-ons in Firefox (or chrome) where they give you more/different software functionality.
