network protocol
Data exchange standard
A network protocol is a standardized set of rules governing how devices communicate over a computer network.
Protocols define how data is formatted, transmitted, and received—ensuring that different hardware and software can exchange information reliably.
Common examples include TCP/IP for internet traffic, HTTP for web pages, and SMTP for email.
The two systems couldn't connect because they were using incompatible network protocols.
