<para>The <emphasis>kernel</emphasis> is the engine of your GNU/Linux system.
|
|
When switching on your box, the kernel is the first part of your operating
|
|
system that gets loaded. It detects and initializes all the components of your
|
|
computer's hardware, then makes these components available as a tree of files
|
|
to the software, and turns a single CPU into a multi-tasking machine capable
|
|
of running scores of programs seemingly at the same time.</para>
|
|
|
|
<para>The <emphasis>kernel headers</emphasis> define the interface to the
|
|
services that the kernel provides. The headers in your system's
|
|
<filename>include</filename> directory should <emphasis>always</emphasis> be
|
|
the ones against which Glibc was compiled and should therefore
|
|
<emphasis>not</emphasis> be replaced when upgrading the kernel.</para>
|
|
|
|
<para>The <filename>System.map</filename> file is a list of addresses and
|
|
symbols. It maps the entry points and addresses of all the functions and data
|
|
structures in the kernel.</para>
