How do you define a protocol?
A protocol is a standard set of rules that allow electronic devices to communicate with each other. These rules include what type of data may be transmitted, what commands are used to send and receive data, and how data transfers are confirmed. You can think of a protocol as a spoken language.
What is meant by protocol in C?
Objective-C allows you to define protocols, which declare the methods expected to be used for a particular situation. This chapter describes the syntax to define a formal protocol, and explains how to mark a class interface as conforming to a protocol, which means that the class must implement the required methods.

A class interface declares the methods and properties associated with that class. A protocol, by contrast, is used to declare methods and properties that are independent of any specific class.
What is Python protocol?
Protocols & Duck Typing Protocol. In Python a protocol is an informal interface. Protocols are either known as an accepted truth or defined in documentation and not strictly in code1.
How do protocols work?
A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.
What are the objectives of protocol?
Aims of the protocol. 1) To raise the question to be researched and clarify its importance. 2) To collect existing knowledge and discuss the efforts of other researchers who have worked on the related questions (Literature review). 3) To formulate a hypothesis and objectives.
Why are protocols needed?
Protocols provide us with a medium and set of rules to establish communication between different devices for the exchange of data and other services. Protocols are needed in every field like society, science & technology, Data Communication, media, etc.
