Udp-port meaning A number assigned to applications and services in a TCP/IP network, such as voice and video calling, that do not require a 100% reliable delivery of packets. See UDP and TCP/IP port.
What is the difference between TCP and UDP ports?
TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.
What is the use of UDP port?
UDP uses a simple connectionless communication model with a minimum of protocol mechanisms. UDP provides checksums for data integrity, and port numbers for addressing different functions at the source and destination of the datagram.
What does it mean if your UDP port is open?
Send a User Datagram Protocol (UDP) packet. After sending the UDP packet, if you receive ‘ICMP port unreachable’ message, then the UDP port is closed. If not, then the UDP port is open or something is blocking the ICMP.

Is it normal to use both TCP and UDP ports?
We will introduce the list of the ports with short description of different port types. Using both TCP and UDP is also normal sometime. Some applications may use both TCP and UDP. For example, the low overhead of UDP with his short header enables DNS to serve many client requests very quickly.
