Question

Accepted Answer

A communication protocol is a set of rules that govern the exchange of data between two or more devices.

Communication protocols define the format, timing, sequencing, and error checking of messages exchanged between devices.
Examples of communication protocols include TCP/IP, Bluetooth, USB, and CAN bus.
Protocols can be either proprietary or open standards.
Protocols can be categorized as either synchronous or asynchronous, depending on whether they require a clock signal to synchronize data transmission.
Protocols can also be categorized as either serial or parallel, depending on whether data is transmitted one bit at a time or in parallel across multiple wires.
