For a clock, a capacitor will fire on a predictable interval.  There is a 
formula by which you can take capacitor value and voltage (an perhaps 
amperage) and get a clock frequency.  The resistor is just there to fix the 
formula to the right clock given the other parts of the circuit.  If you 
need help with electronics stuff, there are a number of good web sites, or 
the TI-H list.
