Network protocol

A network protocol is a set of rules and standards that enable devices, like computers and smartphones, to communicate effectively over a network. Think of it as a common language that ensures data is sent, received, and understood correctly between different devices. Protocols specify how messages are formatted, how to establish connections, and how to handle errors, making sure information flows smoothly and securely across the network. Examples include HTTP for web browsing, FTP for file transfer, and TCP/IP for general internet communication.
