Need more info on internals of c compilers

Hello Gurus,

i am ok with the concepts of c language but i would like to know
more about the internals of c with respect to the compilers

what happens when we say
gcc filename.c

the a.out will get created(what actaully compiler does to the code inaddition to generating object code)

gcc -c filename.c ( )

creates only .o files we need to link them to get a.out(i need extra)

gcc -o fn filename.c ( )

request you to provide me the more info on following
symbol table( how the linker actually uses this info),virtual address(what is this why its needed), physical address(what is this why its needed),linker,loading,locating.
expecting the above with repect to the gcc compilers

NAME
gvrng - An interactive, introductory programming language. SYNTAX
gvrng [world file | program file] DESCRIPTION
Guido van Robot is a project developed by advanced high school students for use by their peers as a learning tool and precursor to the fur- ther study of programming with Python. It is a minimalistic programming language providing just enough syntax to help students learn the concepts of sequencing, conditional branching, looping and procedural abstraction. It's biggest strength is that it permits this learning in an environment that combines the thrill of problem-solving with instant visual feedback. In short, it is an interactive, introductory programming language that is excellent for learning the basic concepts of programming, applicable in any high-level language. Best of all, it's a whole lot of fun, too! At this point, you are probably asking yourself, "What is GvRng, specifically?" The gist of it is that it is a robot represented by a tri- angle on the screen that moves around in a world made up of streets and avenues, walls and "beepers", which Guido can collect or set. His actions are completely guided by a program written by the user. FILES
