Which delivery method does not guarantee that the packet will be delivered fully without errors?

One of the services provided by TCP is reliable data delivery.  We know from lecture that reliable delivery does not mean an absolute 100% guarantee that nothing will ever go wrong. Which of the following are services that TCP attempts to ensure (select all that apply)?Group of answer choicesTransmitted data is guaranteed to arrive at the destination.The sender and receiver will be notified if data is lost in transmission and can not be recovered.TCP can detect if data is intentionally altered during transmission and if it is altered TCP will not deliver the data.TCP ensures data will arrive at the receiver in the same order it was sent.TCP can detect if data is accidentally corrupted during transmission and if it is TCP will not deliver the data.

___________may be invoked when the vendor fails to give the delivery on time or is found deficient at the time of carrying out acceptance tests.

Check all of the services below that are provided by the UDP protocol.Group of answer choicesA congestion control service to ensure that multiple senders do not overload network links.In-order data deliveryA message abstraction, that preserves boundaries between message data sent in different socket send calls at the sender.A guarantee on the maximum amount of time needed to deliver data from sender to receiver.A guarantee on the minimum amount of throughput that will be provided between sender and receiver.Reliable data delivery.A flow-control service that ensures that a sender will not send at such a high rate so as to overflow receiving host buffers.A byte stream abstraction, that does not preserve boundaries between message data sent in different socket send calls at the sender.
