What is the main difference between software models and software discovery models?

The distinction between software models and software discovery models is centered around their purposes and the processes they represent. A software discovery model is specifically created in response to the identification of a new version or instance of software within an organization's environment. This means the discovery model is a critical tool used to document and manage the software that has been found, including its version information, configurations, and licensing specifics.

Thus, when a version of software is discovered, a discovery model is established to facilitate the management and oversight of that software within the broader context of software asset management. This process is essential for ensuring accurate tracking and compliance with licensing agreements, which is a fundamental element of effective software asset management practices.

The other options do not accurately describe the relationship or characteristics of software and discovery models, as they either misrepresent the concepts or overly generalize about the nature of software models.
