Different from a connectionless protocol, a connection-oriented protocol guaranties the delivery of the information. An example of connection-oriented protocol is (TCP) and a connectionless protocol is (UDP). page/926 A+
A datagram socket represents a connectionless, non-guaranteed communication protocol. It represents the UDP protocol in the TCP/IP suite.Contrast this with a stream socket, which represents a connection oriented, guaranteed, communication protocol. It represents the TCP protocol in the TCP/IP suite.UDP is the underlying protocol for TCP. If you are talking OSI model, UDP is layer 3, and TCP is layer 4.
connectionless protocols. A connection less protocol's lack of sophistication makes it more efficient than a connection-oriented protocol and renders it useful in situations in which data must be transferred quickly
HTML is synchronous because the base protocol, HTTP (Hypertext Transfer Protocol) does not maintain a connection with the server. This was because, at the time, no one could imagine wanting a protocol that kept state. Give that the protocol doesn't track the user, there'd be no way for HTML to by asynchronous.
When one computer1 connects to computer2, the first thing it has to do is contact computer2 and tell it who it is and that it wants to connect. Computer2 then must decide to accept (or deny or ignore) the connection and then tell Computer1 that the connection is accepted. The protocol is just the series of technical rules that this basic process must follow. For example, when a tcp connection is initiated by compter1 the protocol is to send a SYN packet to a specific port on Computer2. Computer2 then, if accepting the connection, sends an ACK packet back to Computer1. From that point on the tcp connection is considered open and all future packets will have both the SYN and ACK bits until the connection is closed.
Different from a connectionless protocol, a connection-oriented protocol guaranties the delivery of the information. An example of connection-oriented protocol is (TCP) and a connectionless protocol is (UDP). TCP is a connection-oriented protocol, it makes a connection and checks whether the data is received, and resends if it is not. UDP is a connectionless protocol, it does not guarantee delivery by first connecting and checking whether data is received.

The Novell protocol is SPX
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
In a connection-oriented communication,there is a guaranteed delivery of data : any data that is not received by the destination system is re-sent by the sending device. Communication between sending and receiving device continues until the transmission has been verified. Because the connection-oriented protocol has higher overhead, it places greater demand on the bandwidth. In contrast to connection oriented communication, connection less protocol offers only a best effort delivery mechanism because the information sent there has no conformation that data has been received. If there is error in transmission there is no mechanism to resend the data, so transmission by the connection less is no guarantee that the data is received by the destination. Connection less communication requires far less overhead than connection oriented communication. It is popular in applications such as streaming audio and video where small number packets might represent a significant problem.
Email runs SMTP (simple mail transfer protocol), where SMTP operates over TCP protocol, so it id connection oriented.
One of the benefits of web applications is that they are generally transported via TCP, which is a connection-oriented protocol designed to assure delivery.
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
Connection oriented is more reliable because there is an acknowledgment received from data receiver (destination) that the data is receiving and transfer is successful which is not received from connection less protocol.
