UPD packet delivery

Question

How UDP can transfer packet using only logical address (Which is dynamic) without even creating connection with other device?

Answer 1

Hi Rishabh
dynamic addressing and UDP are not synonymous. ie you can have dynamic addressing in TCP, and you could have static Addressing in UDP.
Addressing and routing is a lower layer function of the network, so packets will get to their destinations as long as the address is valid whatever the protocol, as it will be taken care of by the switch, router or DHCP server depending on your network configuration.
Difference between TCP and UDP is there can be packet loss with UDP, and the Application typically does not care too much, eg Video conferencing or streaming.
