network protocols
Digital handshake rules
Network protocols are standardized rules governing how data is transmitted between devices on a computer network.
They specify formats, timing, sequencing, and error handling so that different systems can communicate reliably.
Common protocols include TCP/IP for internet traffic, HTTP for web pages, and SMTP for email.
The firewall blocked traffic that didn't follow approved network protocols.
