A 'protocol' is a set of invisible computer rules that govern how data gets transmitted to your screen. In networking they standardise the way different devices talk to one another – sometimes known as a handshake.

The internet layer is also responsible for routing of IP datagrams. The transport layer establishes communication between the source and destination hosts and permits them to carry on a conversation
