Question: Which of the following does UDP provide?

Answer:

UDP (User Datagram Protocol) performs the following functions:

Multiplexing and demultiplexing: UDP uses source and destination port numbers to multiplex and demultiplex data across different applications running on the same host.
Data encapsulation: UDP adds a header to the data received from the application layer, which includes the source and destination port numbers, as well as the length and checksum fields.
Connectionless communication: UDP does not establish a connection before sending data, nor does it maintain any state information about the ongoing communication.
Best-effort delivery: UDP does not guarantee the delivery of data packets, nor does it ensure the order of delivery. It simply sends the packets and hopes they reach the destination.

Overall, UDP provides a lightweight and fast transport layer protocol that is suitable for applications that do not require reliability or ordered delivery of data, such as multimedia streaming or online gaming.
