Terminology: In computing, what does the acronym OSS stand for?

Introduction / Context:
Acronyms are common in technology, and understanding them helps in reading documentation and participating in technical discussions. OSS is a foundational term in software development culture and licensing.

Given Data / Assumptions:

• We are discussing general software terminology.
• OSS refers to software whose source code is available under permissive or copyleft licenses.
• Alternative expansions listed are distractors.

Concept / Approach:
Open Source Software (OSS) is software released with a license that grants users rights to inspect, modify, and redistribute the source code, subject to license terms. This ecosystem encourages collaboration, transparency, and rapid iteration across communities and organizations.

Step-by-Step Solution:

Verification / Alternative check:
Consult recognized bodies (e.g., Open Source Initiative) and common usage across documentation, package managers, and repositories (GitHub, GitLab).

Why Other Options Are Wrong:
Open System Software, Original Source Software, Original System Server: Not standard expansions of OSS in this context. None of the above: incorrect because “Open Source Software” is correct.

Common Pitfalls:
Confusing OSS with FOSS (Free and Open Source Software) or with freeware (free of charge but not necessarily open source). Licensing rights vary; always read the license.

Final Answer:
Open Source Software
