OS
OS is TechWorld's operating-system desk — the software underneath everything. Linux, Windows, Android, and iOS: how they work, how to tame them, and how to pick the right one for the job.
What you'll find here
- Linux — distros, terminal skills, servers, and the open-source tools worth your time.
- Windows — power-user tips, troubleshooting, and making Windows behave.
- Android — under-the-hood guides, customization, and getting more from your device.
- iOS — iPhone and iPad internals, settings deep-dives, and getting the most from Apple's walled garden.
How we cover operating systems
- Practical over purist. Use the right tool for the job — we won't shame your OS choice.
- Terminal-friendly. Commands are explained, not just pasted. You'll know what each one does before you run it.
- Tested steps. Every guide is walked through on a real machine before it ships.
