Software distribution models — PC-Write example: The powerful text editor PC-Write was distributed for general use with a small voluntary fee. Such programs are commonly referred to as what?

Introduction / Context:
Many classic PC utilities, including editors like PC-Write, were distributed under a try-before-you-buy model. Understanding the naming and expectations of this model helps learners distinguish licensing from technical categories such as firmware or general software.

Given Data / Assumptions:

• The example is a text editor widely shared in the early PC era.
• Users could try the full program and were encouraged to pay a modest registration fee.
• No hardware embedding or manufacturer lock-in is implied.

Concept / Approach:

The term shareware describes software distributed freely for evaluation with an expectation or request for payment if the user continues to use it. It contrasts with freeware (no payment requested), commercial boxed software (paid up front), and firmware (code stored in nonvolatile memory within hardware).

Step-by-Step Solution:

Verification / Alternative check:

Historical materials and magazine ads from the era labeled PC-Write and similar products as shareware, often including a registration address and suggested price.

Why Other Options Are Wrong:

• Software: too broad; all programs are software.
• Firmware: hardware-embedded code, not a distribution model.
• Mindware: not an industry term here.
• None of the above: incorrect because shareware is the precise label.

Common Pitfalls:

Confusing shareware with freeware or open source. Shareware may be closed source but allows evaluation without immediate purchase.

Final Answer:

Shareware
