What is the difference between root port and designated port in STP?

Herein, what is a designated port in STP?
Designated port—A designated port is a non-root port that is permitted to forward traffic. Designated ports are selected on a per-segment basis, based on the cost of each port on either side of the segment and the total cost calculated by STP for that port to get back to the root bridge.
Beside above, how does STP choose root bridge? The root bridge is selected by manually configuring its bridge priority to a low value. 32768 is the default value out of a range from 0 to 61440. If all switches in a single spanning tree have the same bridge priority, the switch with the lowest MAC address will become the root bridge.
Secondly, can a root port be a designated port?
A Root Port can never be a Designated port. A Root Port is the port on the Switch with the least cost from the "Switch" to the Root Bridge. A Designated Port is the port on a "Local Area Network (LAN) segment" with the least cost to the root bridge.
How do you check if a port is blocked?
Checking Windows Firewall for blocked ports
- Launch Command Prompt.
- Run netstat -a -n.
- Check to see if the specific port is listed. If it is, then it means that the server is listening on that port.
