- 16.It's important that you understand the connection-oriented portion of the Transport layer. Before a transmitting host starts to send segments down the model, the sender's TCP process contacts the destination's TCP process to establish a connection. What is created is known as a__________ _________.
- 17.______ _________ provides a means for the receiver to govern the amount of data sent by the sender. It prevents a sending host on one side of the connection from overflowing the buffers in the receiving host — an event that can result in lost data.
- 18.Data integrity is ensured at this layer by maintaining flow control and by allowing users to request reliable data transport between systems.
