(1) Real time application like video conferenicing needs udp (B'coz it's faster)

-An UDP datagram is used in Network File System (NFS), DNS, SNMP, TFTP etc.

- It has no handshaking or flow control. It not even has windowing capability

- It is a fire and forget type protocol.

- An application can use a UDP port number and another application can use the

same port number for a TCP session from the same IP address.

(2) UDP and IP are on different levels of the OSI stack and corresponds to

other protocols like TCP and ICMP.
