What is protocol?
Answer from a Native speaker
In this video, "protocol" is a tech term that refers to the standard set of rules that allow electronic devices to communicate with each other. This involves what type of data may be transmitted, what commands are used to send and receive data, and how data transfers are confirmed. It is similar to a spoken language. Ex: I'll give you access to my Internet protocols. Ex: Tony gave Peter access to his communication protocols.
