GNU/Linux
 Linux is the kernel: the program in
the system that allocates the
machine's resources to the other
programs that you run.
 The kernel is an essential part of an
operating system, but useless by
itself; it can only function in the
context of a complete operating
system. Linux is normally used in a
combination with the GNU
operating system: the whole system
is basically GNU, with Linux
functioning as its kernel.
