What is one feature that distinguishes shareware from public-domain software?

Shareware is characterized by its trial-based model, wherein users can try the software for a limited time or with limited functionality before deciding whether to purchase a full license. This unique approach allows users to evaluate the software's features and effectiveness in meeting their needs before committing financially.

In contrast, public-domain software is entirely free and does not have any restrictions on its use or distribution. While some may assume shareware is free, it is essential to recognize that it often mandates a payment after the trial period if users wish to continue utilizing the full version of the software. This model incentivizes developers to offer a taste of their product while also generating revenue from those who find value in it.
