What is the differene between the root port and the designated port? Are the 2 below assumptions correct?

1. Every switch/bridge must have one and only one root port, but it does not have to have a designated port.

2. Every VLAN must have one and only one designated port from among all the bridges/switches that have ports in that VLAN. Regular traffic packets, not BDPUs, between root bridge and all ports in that VLAN on all bridges/switches must send and recieve packets through the designated port. In sum, The designated port does not send or recieve BPDU packets.
