    are you referring to communicating between vlans on different switches?

    If so is there something specific you are having problems with.

    Are you referring to inter-vlan routing (trunks, subinterfaces, etc), or are you referring to VTP or just Ethernet in general?

    a trunk allows multiple vlans to traverse a link

    in order to distinguish which vlan each packet belongs to an encapsulation is needed. otherwise the device receiving packets would have no way of sorting which packet belongs to which vlan and they would all look the same

    They allow electrical signals to be passed between computational systems that have certain differences between them.
