Understanding network protocols is key to successful communication between devices on a network.
These protocols define the format, timing, sequencing, and error control of messages exchanged between devices, regardless of their software and hardware differences.
The Internet Protocol (IP) and Transmission Control Protocol (TCP) are two examples of network protocols that serve different purposes.
Network protocols are often categorized by which OSI model layer they belong to, with each layer representing a different category of networking functions.
In short, network protocols are essential for enabling communication between devices on a network by providing a common language for computers to use.
