These protocols require that a logical connection be established between two devices before transferring data. This is generally accomplished by following a specific set of rules that specify how a connection should be initiated, negotiated, managed and eventually terminated. Usually one device begins by sending a request to open a connection, and the other responds ' like telephone call'.

Is DNS connectionless or connection-oriented?
DHCP is a connectionless protocols. In general, any protocol that is based on TCP port alone is a connection-oriented protocol while any protocol that is based on UDP port alone is a connectionless protocol. And a protocols that can work on both TCP and UDP port can be either a connection-oriented or a connectionless protocol depending upon the which protocol is used (TCP or UDP). For checking other protocols if they are connection-oriented or connectionless check http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
What are two features of the User Datagram Protocol UDP?
flow control low overhead connectionless connection-oriented sequence and acknowledgements
What is the purpose of TCP or UDP port numbers?
The purpose of TCP is a connection oriented protocol, meaning that protocol establishes a connection or session between the sources and destination device prior to sending the data segment. UDP is transport layer protocol that provides an interface between the application layer and the network layer.
What is Connectionless and Connection Oriented?
Connection-Oriented means that when devices communicate, they perform handshaking to set up an end-to-end connection. Connection-Oriented systems can only work in bi-directional communications environments. Connection-less means that no effort is made to set up a dedicated end-to-end connection. Walkie-talkies, or Citizens Band radios are a good examples of connection-less communication.
What the protocols establish a connection with another node before they begin transmitting data?
In circuit switching, a connection is established between two network nodes before they begin transmitting data.
