This network diagram illustrates how data is transmitted using the User Datagram Protocol (UDP). It shows the sender and receiver exchanging request and response packets without establishing a formal connection. Each data segment includes a UDP header containing source port, destination port, length, and checksum fields. The diagram highlights UDP’s simplicity and speed, emphasizing that it sends multiple responses quickly without waiting for acknowledgment. This connectionless communication model makes UDP ideal for real-time applications like gaming, voice, and video streaming, where speed and low latency are more critical than guaranteed delivery.
