Explanation
UDP (User Datagram Protocol) is connectionless because it sends datagrams directly to the destination without first establishing a formal connection, performing handshaking, or guaranteeing delivery, order, or error checking. This makes it faster but less reliable than connection-oriented protocols. TCP is connection-oriented, requiring a three-way handshake before data transfer. X.25 is a connection-oriented packet-switched protocol that establishes virtual circuits. Packet switching is a networking technology, not a specific protocol, and many packet-switched protocols are connection-oriented.
