The set of rules that govern the exchange of information over a network is called protocols. These protocols define how data is transmitted, received, and processed across the network. They also ensure that the data is transmitted in a reliable, secure, and efficient manner.

Some examples of network protocols include TCP/IP, HTTP, FTP, and SMTP.
