They are just pieces of compiled C code. There is a big overlap between modules and drivers, but they are not the same. The term driver is usually applied to code controlling hardware devices, while modules may do other things, eg encryption. Also a driver might be a kernel module, or it might be in the kernel proper, or it might be completely outside the kernel, in "userland". -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
