UDP
. A Explain the overview of UDP messaging.
The four key features of User Datagram Protocol (UDP) are: Connectionless Communication: UDP does not establish a connection before sending data, allowing for faster transmission without the overhead of connection setup. Unreliable Delivery: There is no guarantee that packets will arrive at their destination or that they will arrive in the correct order, making UDP suitable for applications where speed is prioritized over reliability. Low Latency: Due to its lightweight nature, UDP minimizes latency, making it ideal for real-time applications such as video streaming and online gaming. No Flow Control or Congestion Control: UDP does not implement flow control or congestion control mechanisms, which can lead to packet loss in congested networks but allows for continuous data flow.
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.
UDP is a layer 4 (transport) protocol.
Routers Drop a lot of UDP packets
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.
