220.127.116.11. The kernel
The kernel is the heart of the system. It manages the
communication between the underlying hardware and the peripherals.
The kernel also makes sure that processes and daemons (server
processes) are started and stopped at the exact right times. The
kernel has a lot of other important tasks, so many that there is a
special kernel-development mailing list on this subject only, where
huge amounts of information are shared. It would lead us too far to
discuss the kernel in detail. For now it suffices to know that the
kernel is the most important file on the system.
