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.
