-The diagram below shows how data is encapsulated and de-encapsulated when transmitting over the network. - Step 1: When Device A sends data to Device B over the network via the HTTP protocol, it is first added an HTTP header at the application layer. Step 2: Then a TCP or a UDP header is added to the data. It is encapsulated into TCP segments at the transport layer. The header contains the source port, destination port, and sequence number.
