Connectionless Service

Abbreviated as COS, connectionless service is one of two techniques used in data communications to transfer data at the Transport Layer (Layer 4). A connectionless service does not require a session connection between sender and receiver; the sender starts sending datagrams to the destination. In contrast with a connection-oriented service, this is less reliable but faster.
