What is a protocol?

Short answer. A set of rules devices follow when they communicate.

Why do different makers' devices still work together?

Because they all follow the same protocols.

A protocol fixes

The format of the data
The order of messages
What to do on errors

Remember

Protocol = agreed rules

Different phones, one network. How do they understand each other? A protocol is a set of agreed rules. It fixes data format. It fixes message order. It says how to handle errors. Remember. Protocols are agreed rules for every device.
