  1. Richard Stallman founded which organization to promote software freedom?

    Answer: Free Software Foundation

    Richard Stallman founded the Free Software Foundation (FSF) in 1985 to support the free software movement and the GNU Project.

  2. Which of the following is NOT one of the four essential freedoms defined by the Free Software Foundation?

    Answer: The freedom to sell the software for profit

    The FSF's four freedoms cover running, studying, redistributing, and improving software; commercial sale is not one of the four defined freedoms.

  3. What does a 'dual-license' model mean for open source software?

    Answer: The software is released under two different licenses simultaneously, offering users a choice

    A dual-license model means the software is released under two licenses at once, often one open source (e.g., GPL) and one commercial, giving users or companies a choice.

  4. Which license requires that patent rights held by contributors be granted to all users of the software?

    Answer: Apache License 2.0

    The Apache License 2.0 includes an explicit patent grant, ensuring contributors' relevant patents are licensed to all recipients of the software.

  5. What is the primary purpose of a software license in open source projects?

    Answer: To define the legal terms under which the software can be used, modified, and distributed

    A software license sets the legal terms governing how software may be used, modified, and distributed by others.

  6. In which scenario would you need to comply with the GPL's source code disclosure requirement?

    Answer: Distributing a binary built from GPL source code to others

    GPL's source disclosure obligation is triggered by distributing binaries to others; private use or internal modification does not require disclosure.

  7. Which term describes software that was once proprietary but has been released by its owner under an open source license?

    Answer: Open-sourced software

    When a vendor releases previously proprietary software under an open source license, it is commonly called 'open-sourced' software.
