What is the type of software that has no intellectual property protections?

Freeware refers to software that is available for use at no cost, but it typically retains copyright protections. Users can download and use freeware for free, but the original creators maintain ownership and control over the software, which prevents modification and redistribution without permission.

Shareware is a type of software that is distributed for free on a trial basis, after which users are expected to pay for continued use. Like freeware, shareware is still protected by copyright law, meaning that it cannot be freely modified or redistributed without authorization from the copyright holder.

Closed-source software is proprietary software where the source code is not available to the public. This type of software is protected by copyright, and users must adhere to the licensing agreements that restrict usage and distribution. Thus, closed-source software cannot be modified or shared freely.
