Consider two processes communicating over a TCP/IP network using the TCP protocol on an Ethernet network. As data from a sending process moves through the protocol stack each layer will encapsulate the payload and generate a Protocol Data Unit (PDU) which is then passed down to the next lower layer. Prepare a diagram illustrating the layers, direction of data flow, peer layer communication, and identify the PDU name and the structure of components (structure) of the PDU and explain encapsulation steps for each layer.
