FAQ
Common questions
Quick answers before you dive in.
Why simulations instead of just reading theory?
Because action recognises concepts better than theory alone. The Druvexaa method is: learn the theory brief, then visualise it in 3D — trigger the process yourself, watch it happen, and it locks in. What you only read, you revise; what you see and do, you never forget.
Is Druvexaa free?
Yes — every simulation, quiz, and downloadable material on the site is completely free to use.
Do I need to install anything?
No. Everything runs directly in your browser — the simulations are built with web 3D technology, so just click and explore.
Can I use it on my phone?
The site works on mobile, but the simulations are highly visual and interactive — we strongly recommend a desktop or laptop for the best experience.
The voice narration isn't playing — what do I do?
Make sure your sound is on and click anywhere inside the simulation once (browsers block audio until you interact with the page). If it still doesn't play, try Chrome or Edge.
The 3D scene is slow or laggy — how can I fix it?
Close other heavy tabs, and make sure hardware acceleration is enabled in your browser settings. On laptops, plugging in the charger often unlocks full GPU performance.
In what order should I do the networking simulations?
Recommended path: Network Types → OSI Layers → Hub → Switch → ARP → DHCP → DNS → TCP vs UDP → Topologies → VLAN → VPN → Firewall. That mirrors most university syllabi.
Are the quizzes graded or saved?
Quizzes show your score instantly so you can check your understanding on the spot. You can retake them as many times as you like.
I'm a teacher — can I use these in class?
Absolutely. The simulations are made for classrooms: project them, run the guided walkthrough, and use the quiz for instant assessment. Reach out via the contact widget on the homepage for anything specific.
Where do I download the study materials?
On the homepage, just below the search bar, follow the "Download Materials" arrow — textbooks and notes are available there.
Something is broken or I have a suggestion — where do I report it?
Use the feedback/rating widget on the homepage — every message is read, and suggestions regularly become new simulations. You can also mail us directly at druvexaa@gmail.com — we'll get back to you as soon as possible.
Which browser works best?
Chrome and Edge give the smoothest 3D performance and the most reliable voice narration. Firefox works well too; Safari is fine for most sims but narration voices can vary.
How long does one simulation take?
Most take 7–12 minutes including the guided walkthrough. Quick ones like Network Hub are under 5 minutes; deeper ones like TCP vs UDP or VLAN can take 15 if you explore everything.
Do the simulations match my university syllabus?
Yes — the topics map to standard B.Tech / BCA / MCA computer networks, operating systems and hardware units. Use the category order in the directory above and you'll cover the syllabus sequence naturally.
Will new simulations be added?
Yes, new simulations are released regularly — recent additions came directly from user requests through the feedback widget. If a concept you need is missing, ask for it.
Can I share a simulation with my classmates?
Please do — every simulation has its own link, so you can send exactly the topic your friend is stuck on. Sharing is the biggest way the project grows.
