Explain How do applications coexist over TCP and UDP?


Each application running over TCP or UDP distinguishes itself from
other applications using the service by reserving and using a
16-bit port number. Destination and source port numbers are placed
in the UDP and TCP headers by the originator of the packet before
it is given to IP, and the destination port number allows the
packet to be delivered to the intended recipient at the
destination system.
