Hello, I want to ask a couple of questions about the Linux Kernel.

1. What are the components of the Linux Kernel?
   

2. Does the Linux Kernel include a C compiler and a Terminal to interface with?
   

3. Can I compile a Linux Kernel and install it on a PC without an existing Operating System? If yes is there any website for a tutorial on how to do it?
   

4. Can I compile a GUI-Desktop shell to work with the Linux Kernel?

Thank You
