Shareware refers to fully functional proprietary software that is available for free on a trial basis, allowing users to evaluate its features and capabilities before making a purchase decision. This model is designed to entice users to try out the software and subsequently decide whether to pay for a full version based on their experience during the trial period.

The nature of shareware is to provide users with the opportunity to explore the software's functionality without upfront costs, but often includes some limitations, such as a time restriction or a reduced feature set, prompting the user to eventually purchase a license for full access. This approach helps software developers reach a wider audience and allows prospective buyers to assess the product's suitability for their needs before committing financially.

In contrast, other options outline different types of software models. Software that is always free to use does not fit the shareware definition, as it does not involve any trial period or purchase. Open-source software is fundamentally different, as it allows users to view, modify, and distribute the source code without restriction. Software requiring a subscription fee describes a different business model focused on ongoing payments rather than the trial-to-purchase transition typical of shareware.
