A few questions about Linux....

Sorry, I haven't been able to come up with a better title....

I have two questions floating in my mind...
1) The kernel does can many modules which have many functions. But how does the kernel know when to call which function in a certain module? I mean, how does the kernel know in advance which function is responsible to do what it is expected to do?

2) Segmentation faults are "traps", that cause a program to crash if it tries to access reserved memory space. Is this always due to programming bugs?

For the first question, you should take a look at the old kernel book. Some of it is outdated, but it's still a good read.

As far as the seccond question,
You *could* raise SIGSEGV with sigaction or something like it, but I cannot think of any particularly useful application for this.
