broadcast domains in Vlans

I can't understand when a router is needed through switches for VLANS ...

1) In one switch if I create some VLANS , I create both collision and broadcast domains per segments , without a router attached ?

2) I only need a router when more than one switch are connected using VLANS ?

    hi AkuMa

    Router does the job of forwading inter Vlan traffic. It only comes into the picture when traffic is being forwaded between 2 switches.

    i hope i am correct. :D

    I can' t understand if a single switch without a router attached can separate broadcast domain with vlans ... icon_cry.gif

    I haven't gotten to the switching and VLAN parts for the CCNA TechNotes, but maybe this one from Net+ might clear up the basic idea:
