1. IP works at network layer, UDP works at transport layer. 2. UDP carries application data, IP carries TCP segments or UDP datagrams.
provides connectionless, unreliable serviceso UDP faster than TCPadds only checksum and process-to-process addressing to IPused for DNS and NFSused when socket is opened in datagram mode
UDP
. A Explain the overview of UDP messaging.
1)connection less.2)it sends bulk quantity of packets3)no acknowledgment4)good for video streaming5)fast6)and i think it is ISO 3/4 protocol. (kinda sure)
DNS uses both TCP and UDP, also a lot of online chats use UDP. I think even when you want videos on YouTube UDP is used to deliver video and audio.
Routers Drop a lot of UDP packets
UDP is a layer 4 (transport) protocol.
UDP is a connectionless protocol, so there is no session to close. UDP is not expecting any particular packet, so opening and closing via UDP is not necessary.
the main difference between UDP and TCP is that UDP is not a reliable protocol.
