The rules for exchanging data on a network are known as "protocols". These protocols are a set of rules that determine the format, timing, sequencing, and error control of data communication over a network. They provide a common language that allows different devices to communicate with each other efficiently and effectively. Without protocols, devices on a network would not be able to exchange information in a reliable and consistent way. Examples of network protocols include TCP/IP, HTTP, FTP, and SMTP.
