Answer:
The Layer 4 (Transport layer)
Step-by-step explanation:
The transport layer is the fourth layer of the OSI (Open Systems Interconnection) model that is responsible for transmitting data between networking devices. Some of its other functions are;
i. It maintains flow control so that the destination station does not receive more packets than it can handle or process at a particular time.
ii. it also maintains error control so that the entire message (data) sent arrives at the layer without any error due to incompleteness, loss, damage or duplication.
