What is the difference between datagram and packet?
datagram is used in conectionless n/w e.g. UDP Whereas packets used in connection oriented n/w e.g. ATM X.25 tcp
Are Layer 2 protocols connectionless or connection-oriented?
They can be both. E.g. MPLS-TP or Connection-Oriented-Ethernet (COE) are connection oriented.
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+
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.
Difference TCP and UDP?
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
Is UDP connection oriented?
No
What is TCP subprotocol?
Connection-oriented
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.
Why connection oriented is more reliable than connection less protocol?
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.
Which protocol offers guaranteed delivery and is connection oriented?
Transmission Control Protocol (TCP) is used when data reliability is needed since it is connection oriented and guarantees delivery.
How is TCP connection-oriented but IP connectionless?
TCP is known as a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged.that connection is virtual only...
What is the difference between conectionless and connection-oriented protocol?
A connectionless protocol is one where the client does not make a connection to the server. This is typically the UDP subprotocol of TCP/IP. There is one packet sent for each message. The client and server applications are responsible for all validation, sequencing, and acknowledgment issues. Its a little like standing in a field with a megaphone. You yell out your message and, if someone hears it that needs to hear it, they answer with their own megaphone. If you don't get an answer, you wait a bit and try again. A connection-oriented protocol is one where the client establishes a connection for each conversation with the server. This is typically the TCP subprotocol of TCP/IP. There can be many packets sent back and forth during the conversation, but that is no longer the concern of the application. The protocol stacks on each machine are responsible for validation, sequenceing, acknowledgement, retries, etc. Its a little like making a telephone call. You pick up the phone and dial a number. The other party may or may not answer, but when they do you can have a conversation.
