Can someone explain what is proxy setting and how it works? or What is proxy setting and why would I

Proxy settings are your internet’s invisibility cloak. They mask your real IP by routing traffic through another server.

Setup’s easy:
- Windows: Network settings > Proxy
- Mac: System Prefs > Network > Proxy
- Mobile: Wi-Fi settings > Proxy

Speed? Depends on the proxy. Free ones suck, paid ones like NordVPN or VyprVPN are smoother. Only use if you need anonymity or to bypass blocks.
