Communication Protocols are the language used by machines to talk to each other. For communication to be possible, a common language must be spoken and understood by the participants.
What is a Communications Protocol
Communication protocols are written explanations of the formats and regulations of digital messages. They're needed to send and receive communications within and between computer systems. Communication protocols are vital in telecommunications and other systems because they ensure that messages are sent and received in a consistent and universal manner.
Authentication, error detection and correction, and signaling are all covered by communications protocols. They can also characterize analog and digital communications' syntax, semantics, and synchronization.
Hardware and software are used to implement communication protocols. In both analog and digital communications, there are thousands of communication protocols in use. They are required for the operation of computer networks.
