What are some responsibilities of a transport layer protocol?
Create process-to-process communication, provide control mechanisms at the transport level, and provide error control to some extent.
How does UDP accomplish process-to-process communication?
UDP uses port numbers.
What are the disadvantages of UDP?
No flow control mechanism, no acknowledgment for received packets, and it silently drops packets if an error is detected.
Why would a process want to use UDP despite its disadvantages?
UDP is a very simple protocol with minimal overhead, suitable for sending small messages with less interaction between sender and receiver.
What is the format of a UDP user datagram and what information does it contain?
A UDP user datagram has a fixed-size header of 8 bytes, containing the source port number and other fields.
