Where is FSB?

Here's a dumb question -

Where is the FSB? On the CPU or on the MOBO?

The FSB is essentially the Processor's interface to the rest of the machine,
it is set by the Mainboard but determined by the maximum FSB of both the
processor and attached Memory.

Well then - if my CPU speed is said to be 800MHz and its FSB is said
to be only 200MHz, does that mean my MOBO and CPU are only running at
200MHz? And can I increase the 200 so that processing runs faster?
Or can the MOBO can only handle 200? Help me understand.

It's not "said to be 800MHz", not in same context as
"200MHz" FSB. There is not anything that needs to be
considered here except that anyone can "say" anything but we
don't have to spend time pondering that which is wrong.

Learn about your CPU and board, what they're both spec'd to
do and whether they're running at correct speed. Take
anything "said" with a grain of salt, as intel in particular
has created a joke of a bus speed terminology by not
correcting those that claim "800MHz" for it's busses. 800
is a quad data rate term for a bus running at 4 x 200MHz
clock rate. Not that it's intel's fault per se, same
happens to AMD platforms too but at least they more often
keep the DDR(nnn) nomenclature more often while nobody seems
to use QDR(nnn) for intel platforms.
