Protocols Interview Questions and Answers


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.
