Question 15

Shareware can be used with partial functionality for no cost.

Shareware software allows users to try the software with limited features or for a limited time without any cost. This model encourages users to evaluate the software before making a purchase decision.

A) Shareware

Shareware is a type of software that is distributed for free on a trial basis, allowing users to use limited features or functionalities. It often requires payment for full access, making it a perfect fit for the question regarding software that can be used partially at no cost.

B) Public domain

Public domain software is free to use without any restrictions or limitations. Unlike shareware, it does not offer partial functionality for free; rather, it is completely free and unrestricted, making it an incorrect choice for this question.

C) Closed-source

Closed-source software typically requires a purchase or license and does not provide any free access or partial functionality. Thus, it is not applicable to the question, which specifically asks about software that can be used at no cost.

D) Freeware

Freeware is software that is completely free to use without any limitations on functionality. However, it does not fit the definition provided in the question, which seeks software that allows for partial use before requiring payment, distinguishing it from shareware.

Conclusion

Shareware is the only option that specifically allows for partial functionality at no cost, aligning perfectly with the question's requirements. In contrast, public domain software is entirely free, closed-source software requires payment, and freeware does not offer a trial or partial payment model, making them unsuitable answers.
