Connectionless Protocols: These protocols do not establish a connection between devices. As soon as a device has data to send to another, it just sends it. Answer:
A Connectionless Protocol is a data communication method in which communication occurs between hosts with no previous setup. The device at one end of the communication transmits data to the other, without first ensuring that the recipient is available and ready to receive the data. The device sending a message simply sends it addressed to the intended recipient. The internet Protocol (IP) and User Datagram Protocol (UDP) are connectionless protocols, but TCP/IP (the most common use of IP) is connection-oriented
All protocols in the "internet layer" are inherently connectionless. And really, in the Internet model, the only "internet layer" protocol is IP. On the "transport layer" the two most common protocols are TCP and UDP. TCP is connection-based, and UDP is connectionless. There are several other protocols such as RTP, that have specific purposes like handling media. These are generally connectionless because they are tolerant to small levels of data loss.
The connectionless protocol at the transport layer is UDP (User Datagram Protocol). It is an unreliable (but fast) protocol that does not contain error detection or correction, and is not a reliable delivery mechanism.
A connectionless protocol sends information to a designated IP address and does not wait for a response confirming delivery of the packet. The currently most popular suite that uses this is known as UDP. This is in contrast to TCP, where each packet is part of a "session" or "connection." TCP has higher reliability, but uses more bandwidth than UDP. Connectionless protocols run faster, but there is a greater chance for lost data.

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
Which protocol is connectionless?
UDP!
Explain the difference between a connection-oriented protocol and a connectionless protocol and give an example of each?
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.
Which protocol provides connectionless network service?
In internet protocol suite UDP is the connectionless protocol. There is no initial communication between client and server. UDP will not check whether the transmission was successful.
What type of protocol is useful when data must be transferred quickly?
Connectionless protocols
What are two features of the User Datagram Protocol UDP?
flow control low overhead connectionless connection-oriented sequence and acknowledgements
What are two features of the User Data gram Protocol UDP?
• low overhead• connectionless
Difference between connectionless and connection oriented communication?
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+
How does tftp overcome the limitation of using a connectionless transport layer protocol?
TFTP doesn't really overcome the connectionless transport - it doesn't have to because the idea here is transferring files with speed, not quality. It doesn't matter to the protocol is the information doesn't arrive, or arrive correctly, etc.
Which protocol working at the Transport layer provides a connectionless service between hosts?
There are many connectionless protocols depending on which layer of the OSI model you are referring to. An example would be UDP for transport, and IP for routing.
What is ntp port number?
UDP port 123. (UDP is a connectionless protocol that sacrifices reliability for speed and bandwidth).
When connectionless protocols are implemented at the lower layers of the OSI model?
an upper-layer, connection-oriented protocol or service
