Re:How can find firmware version on router & switch

there is a firmware version (I'm assuming you mean Boot/rommon firmware), which you can kind of consider like your bios on a computer. The only time you may ever need to upgrade that is to support new hardware for that model of router (ie. new expansion cards or something like that).

eg.

ROM: System Bootstrap, Version 15.0(1r)M10, RELEASE SOFTWARE (fc1)

IOS is the main code that the routers run, consider that to be like the operating system on your computer (ie. windows xp or whatever).

eg.

Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.1(4)M4, RELEASE SOFTWARE (fc1)

And Justin showed you how to get the current version of code that you are running.
