kernel can load modules as and when needed. For example, if you have
compiled the kernel making parport and parport_pc as modules; these modules
are not loaded at boot time (until configured to load at boot time by
/etc/modules). Whenever any application needs these modules, kernel loads
the modules first (using modprobe) and then applications can avail the
functionality provided by module.
