Test what you know about Linux with eight Myth-or-Fact questions covering its history, terminology, licensing, security and real-world use. Choose an answer before opening each explanation; the key distinction to keep in mind is that “Linux” technically names a kernel, while a complete system usually includes many other components.
How well do you know Linux? Take the quiz
For each statement, choose Myth or Fact before revealing the answer. In everyday conversation, people often use “Linux” to mean a complete operating system. The explanations below distinguish that familiar shorthand from the more precise technical meaning when it matters.
1. Linus Torvalds wrote a complete operating system by himself in 1991.
Your choice: Myth or Fact?
Reveal the answer and explanation
Answer: Myth. Torvalds began the Linux kernel project in 1991; he did not write every component of a complete operating system alone. The GNU Project had been building a broader free Unix-like system since 1984, and combining GNU components with the Linux kernel made a complete GNU/Linux system. The Linux Foundation dates Torvalds’s personal project to April 1991 and his public announcement to August 1991.

2. Linux was copied from Unix source code.
Your choice: Myth or Fact?
Reveal the answer and explanation
Answer: Myth. Linux is Unix-like and was inspired by Unix principles, but that does not mean it was copied from Unix code. Canonical describes Linux as independent of Unix source code and calls it a “free, community-driven kernel” created in 1991. Inspiration and source-code lineage are different claims.

3. In precise technical usage, “Linux” names the kernel rather than the entire operating system.
Your choice: Myth or Fact?
Reveal the answer and explanation
Answer: Fact. The kernel is the core that manages communication between software and hardware; a complete GNU/Linux distribution combines the Linux kernel with GNU and other user-space programs. The GNU Project recommends “GNU/Linux” for the complete system and “Linux” for the kernel. That distinction is useful for accuracy, though ordinary users commonly say “Linux” when they mean a distribution.
4. “Free software” always means open-source software, and open-source software always costs nothing.
Your choice: Myth or Fact?
Reveal the answer and explanation
Answer: Myth. Price and license rights are separate questions. The Linux Foundation explains that open-source software must make its source available and grant license permissions to modify and redistribute it; software may be free to use without being open source. So “free” can refer to cost, freedoms granted by a license, or both—and the word alone does not settle which.
5. If software’s source code is public, it is automatically secure.
Your choice: Myth or Fact?
Reveal the answer and explanation
Answer: Myth. Publicly visible code is not a guarantee of security, just as visibility alone does not prove software insecure. The Linux Foundation’s position is conditional: “Open source software is secure only if used correctly and responsibly.” Security depends on practices such as secure coding, tracking dependencies, and maintaining software over time.
6. Linux is only a desktop operating system for hobbyists.
Your choice: Myth or Fact?
Reveal the answer and explanation
Answer: Myth. Linux is used well beyond personal desktop computers. A 2026 figure from Linux Foundation Research reports 4 billion Android devices, 200M+ servers, and all 500 of the world’s top supercomputers. These are dated report figures, not a timeless count, but they illustrate the range of deployment contexts.
7. Linux runs on phones as well as on supercomputers.
Your choice: Myth or Fact?
Reveal the answer and explanation
Answer: Fact. Linux’s reach includes mobile devices and high-performance computing, not just desktops and servers. The same 2026 Linux Foundation Research report cited above gives the figures of 4 billion Android devices and all 500 of the world’s top supercomputers. The scale is striking, but the two figures describe different kinds of deployments and should not be treated as a single measure.
8. Saying “Linux” to mean a complete operating system is always technically wrong.
Your choice: Myth or Fact?
Reveal the answer and explanation
Answer: Myth. Technically, the kernel and the complete distribution are distinct, and “GNU/Linux” makes that distinction explicit. But “Linux” is also widely used as everyday shorthand for a Linux-based operating system. The important thing is to clarify which meaning you intend when the distinction affects the explanation.
How should you interpret your score?
Count one point for each correct answer. This score is a check on the concepts in this quiz, not a measure of general computer expertise.
Crashes, No Sound, or Screen Glitches?

Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstall- 0–3 correct: Start with the vocabulary: distinguish a kernel from a complete distribution, then revisit the difference between software price and license rights.
- 4–6 correct: You have the broad picture. Review the explanations where you confused inspiration with copying, or visibility with a security guarantee.
- 7–8 correct: You caught nearly all the distinctions. The main challenge is using “Linux” precisely when discussing the kernel, while recognizing its common shorthand use for a whole system.
For a second pass, try to explain each answer without looking at its reveal. If you can distinguish the kernel from the programs around it, and license freedoms from price, you have the foundations behind most of the quiz.

What is the difference between a Linux kernel and a Linux distribution?
A kernel is the core software that manages how the system interacts with hardware and running programs. A distribution packages the kernel with other software and tools so users have a usable system.
Does an open-source license mean I can do anything I want with the software?
No. The specific license sets the permissions and conditions for use, modification and redistribution. Check the license itself rather than assuming every open-source project grants identical rights.
Can software be open source and still be sold?
Yes. A price is not the same thing as the rights granted by a license, so a charge for software does not by itself establish whether its source is open or what users may do with it.
