A function called adjacent-layer interaction, which refers to the concepts of ___
how adjacent layers in a networking model, on the same computer, work together.
A function called same-layer interaction.
When a particular layer on one computer wants to communicate with the same layer on another computer, the two computers use headers to hold the information that they want to communicate.
TCP/IP defines two versions of IP.
IP version 4 (IPv4) and IP version 6 (IPv6).
The term IP host refers to ___
any device, regardless of size or power, that has an IP address and connects to any TCP/IP network
WAN
