Connectionless protocol

In telecommunications, connectionless describes communication between two network end points in which a message can be sent from one end point to another without prior arrangement. The device at one end of the communication transmits data addressed to the other, without first ensuring that the recipient is available and ready to receive the data.

(In Other Words We Can Say-A Connection-orianted protocol,cilents connects to the server,make request,get response and then maintain the connection to handle Future Requests) eg. File Transfer Protocol (FTP) Some protocols allow for error correction by requested retransmission. Internet Protocol (IP), Hypertext Transfer Protocol (HTTP) and User Datagram Protocol (UDP) are connectionless protocols.

Connectionless protocols are also described as stateless because the endpoints have no protocol-defined way to remember where they are in a "conversation" of message exchanges.
