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.
