UGC NET Questions (Paper – 1)

Open source software is released under licences that grant users rights to access, modify and share its source code. This promotes transparency, peer review and community-driven improvement. Projects like Linux and LibreOffice illustrate how collaborative development can produce robust tools. Therefore the software described in the stem is open source software.

Option A:
Option A is correct because the combination of code availability and redistributable licensing is central to open source definitions provided by bodies like the Open Source Initiative. These conditions go beyond simply being free of cost.

Option B:
Option B, freeware only, denotes programs that can be used without payment but do not necessarily provide access to their source code or modification rights. Many freeware applications remain proprietary.

Option C:
Option C, trialware, restricts use to a limited time or feature set unless a licence is purchased and generally conceals source code. It is a marketing strategy rather than an openness principle.

Option D:
Option D, closed source proprietary, is the opposite of open source, as users cannot see or change the internal code and redistribution is tightly controlled.
