No, it doesn't, at least not necessarily. The Linux kernel includes all 
of the device drivers that are supported by Linux. This is the main 
reason that it is such a big project. These device drivers can either be 
linked statically into the kernel, which makes sense for all stuff which 
is needed during the boot process, or on embedded systems, or compiled 
into kernel modules, kind of "dynamic libraries" of the kernel, which it 
loads/unloads at runtime.

It is most definitely not. Linux runs on a large diversity of platforms. 
It has an elaborate build process, wicth a GUI to configure all the 
compile options. Probably no human would be able to set them to a 
reasonable value without the help of thsi software.
