Connectionless protocols, such as UDP, do not require an acknowledgment (ACK) message from the receiver to the sender. They are designed to provide low-overhead, best-effort delivery of messages, without establishing a dedicated end-to-end connection. Unlike connection-oriented protocols (such as TCP), which require handshaking, sequencing, and error checking to ensure reliable data transfer, the connectionless protocol simply sends the packet to the destination and forgets about it. This makes it faster and more flexible than connection-oriented protocols.
