"I'm Jonathan Ayres with Network for Success and today we are going to talk about what is a protocol. A protocol is a set of standards that is used by computers to transmit data across wires or wirelessly. Now this set of standards is actually hard coded into each computer so that when one computer sends information to another, they are both using the same method for translating that data. The most common protocol in use around the world is TCPIP. And this is a protocol that has an international set of standards on how to be used for sending information and data. It's a very technical subject but basically if you know that TCPIP is the protocol that's being used and that will allow you to understand how data is transmitted across wires."
