The primary definition of a network protocol lies in its role as a set of standard rules that governs how data is represented and how communication takes place between devices over a network. These rules ensure that different devices can understand and properly manage the data being transmitted, regardless of their underlying architecture or operating systems.

Network protocols specify how data should be formatted, transmitted, and received, which includes defining aspects like data packet structure, addressing methods, error handling, and synchronization of communication between devices. This standardization is crucial for enabling interoperability among diverse networking devices and systems.

The other options, while related to aspects of computing and networking, do not capture the essence of what a network protocol is. For instance, software permissions pertain to access control rather than communication standards, hardware management involves maintaining and configuring physical components instead of defining communication rules, and installation tools are concerned with setting up hardware rather than dictating communication methods between networked devices.
