What is the primary purpose of network protocols?

The primary purpose of network protocols is to standardize communication between devices. Network protocols are sets of rules and conventions that dictate how data is transmitted and received over a network. By establishing standardized methods for communication, these protocols ensure that devices from different manufacturers or with different specifications can understand and interpret the data they send and receive. This interoperability is crucial for the functionality of the internet and local networks, allowing diverse systems to work together seamlessly.

Protocols also facilitate various aspects of communication, such as error handling, data compression, and the structure of messages. This standardization is essential for maintaining consistent and reliable communication, which forms the backbone of modern networking.
