Definition
Public Wi‑Fi is a shared network in cafés, airports, or hotels. It is convenient but riskier — prefer HTTPS sites, avoid sensitive logins, or use a trusted VPN.
Real-World Example
Checking email on airport Wi‑Fi is safer over HTTPS or a VPN than entering banking passwords on an unknown open network.
