When an application uses a TCP socket, what transport services are provided to the application by TCP?  Check all that apply.Group of answer choicesThroughput guarantee. The socket can be configured to provide a minimum throughput guarantee between sender and receiver.Loss-free data transfer. The service will reliably transfer all data to the receiver, recovering from packets dropped in the network due to router buffer overflow.Congestion control.  The service will control senders so that the senders do not collectively send more data than links in the network can handle.Flow Control. The provided service will ensure that the sender does not send so fast as to overflow receiver buffers.Best effort service.  The service will make a best effort to deliver data to the destination but makes no guarantees that any particular segment of data will actually get there.Real-time delivery. The service will guarantee that data will be delivered to the receiver within a specified time bound.

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.
