What defines a network protocol?

A network protocol is defined as a set of rules for transmitting and receiving data over a network. This definition encompasses the guidelines and standards that determine how data is formatted, transmitted, and processed, allowing different devices and systems to communicate with one another effectively.

Protocols ensure that the transmitted data is understood and correctly interpreted by the receiving device, covering aspects such as error handling, data compression, and encryption. Examples of commonly used network protocols include TCP/IP, HTTP, and FTP, each serving specific functions in data communication.

The focus on the set of rules highlights the necessity for consistency and reliability in data exchange across diverse networked systems, which is crucial for the proper functioning of the internet and other communication networks.
