Show answer & explanation
Correct answer: D
In networking, a connection-oriented service establishes a connection before data transfer and provides reliable communication, including error checking, acknowledgment, and ordered delivery of packets. An example is TCP (Transmission Control Protocol).
A connectionless service does not establish a dedicated connection before sending data and does not guarantee reliable delivery or packet order. An example is UDP (User Datagram Protocol).
