Proprietary software refers to programs that are owned by an individual or a company, granting that entity full control over its use, distribution, and modification. This means that users need permission to access the source code, make alterations, or redistribute the software. Proprietary software typically comes with a license that outlines how it can be used, which often requires payment or subscription to maintain legal access.

In contrast, open-source software allows users to view, modify, and distribute the source code, fostering collaboration and innovation. Freeware is software that is available for use at no monetary cost but may still have restrictions regarding modification or redistribution. Shareware is a type of software that is distributed on a trial basis and often requires payment for continued use, but may allow users to explore functionalities before purchasing.

Understanding these distinctions is crucial for navigating software licensing and development, especially in environments that prioritize security and compliance.
