UGC NET Questions (Paper – 1)

Open source software grants users the freedom to inspect how programs work, adapt them to local needs and share improvements with the community, subject to licence conditions. This can reduce dependency on single vendors and encourage innovation and collaboration. Proprietary software typically withholds source code and imposes strict licensing terms, giving users limited rights to modify or redistribute. The contrast in code openness and user freedoms is central to the definition.

Option A:
This option correctly identifies that open source is defined by the freedoms granted by its licence regarding source code use and modification. Universities often choose such software to avoid lock-in and to support local customisation and research.

Option B:
Cost alone does not determine whether software is open or closed; some open source products offer paid support, and some proprietary products may be temporarily free. The crucial issue is access to source code and legal permissions.

Option C:
Binding usage to one specific hardware brand and daily licence renewal are examples of very restrictive proprietary practices, not defining features of open source models.

Option D:
Printed code listings may accompany software, but without executable binaries and licences, they do not constitute usable open source. Open source must be both available and legally modifiable in digital form.
