A protocol is a set of rules and guidelines established for communication or data exchange between two or more devices or systems. It defines the format, semantics, and rules for exchanging data, ensuring that the transmitted information is understood and processed accurately by the recipient. Protocols can be used in various contexts, such as computer networks, internet, wireless communication, and even in business or social situations. Some examples of protocols include TCP/IP, HTTP, FTP, SMTP, and others.
