I have used boson simulation software i created 2 routers and 2 switches and two pc's the pc's are in different subnets after configuring the serial dce dte and bringing up the interfaces and assigning them ip addresses and adding a couple of routes i ended up being able to route between the two pc's on different subnets. I used the 2501 and the 2514. Does that mean if i had a real 2501 and 2514 and the 1900 switches i should beable to do the same thing in a real enviorment ?

Router on a stick is refering to utilising VLAN Trunking to a router to then route between the VLAN and send the traffic back to the switch on the correct VLAN.
If you have for example 4 VLAN's configured on your switch and you create a VLAN TRunk to the router, the router is then able to route between the VLAN's using the 802.1q/ISL trunking to encapsulate the VLAN traffic.
Basically, the VLAN2 traffic goes to the router, the router will then de-encapsulate the VLAN information, see where its being sent to (i.e. a different VLAN down the trunck), it will then re-encapsulate the packet with the new VLAN (say VLAN4) and then send it down the trunk to the switch, its then tagged for the correct VLAN
