Odd programming question

[trekiej]

I appreciate all replies.

In the end I guess I will need to get into Kernel Dev to get the full understanding.

On a side note, do files have headers.  I do not mean xxx.h in a C program.  Is this not how an OS knows the difference between files?
@Karlos:
That is where I want to head with this.  I may get into Kernel Dev. with Linux but may go a non-programming route with my career.

You can do that if you want to understand *internals* of a particular kernel, otherwise I'm not sure exactly what you want to understand, but if it is what I *think* it is then you better learn to write some code in asm. calling OS functions (APIs) in asm will show you what you want to know I'm guessing.

@Einstein: Maybe one day I will.  I have too much to do and need a job to go further.  I have a part-time job but it is not enough.  I like too much technology and need to pick one and go with it.
