First, you know the story: init starts. You can read in /etc/inittab:

si::sysinit:/etc/rc.d/rc.sysinit

That script runs once on start. Then, on the same inittab, you see

l1:1:wait:/etc/rc.d/rc 1

That script runs for each runlevel change. In that script you can see:

...
for i in /etc/rc$runlevel.d/K* ; do
...
for i in /etc/rc$runlevel.d/S* ; do
...

You can see that the first loop executes al K* commands. See that
directories. K stands for kill, and K files are sorted with numbers, to
force preferences. Then S scripts are executed. When you make a
chkconfig, this files are created for every runlevel. 

Ok?
