1.8 NETWORK PROTOCOLS
A network protocol is a set of rules that govern how data is exchanged between devices connected to the same
network. In essence, it enables connected devices to interact with one another despite variations in internal operations,
structure, or design. Network protocols are responsible for allowing you to interact with individuals all over the world,
and they play an important part in modern digital communications.
Network protocols enable devices to connect with each other by preset rules embedded into device software and
hardware, similar to how speaking the same language facilitates communication between two humans. Without the use
of network protocols, neither local area networks (LANs) nor wide area networks (WANs) could function as they do today.
