A VPN (Virtual Private Network) encrypts your internet connection and hides your IP address by routing your traffic through a secure server, making your online activity private and harder to track. It protects your data from being seen by your internet provider, hackers on public WiFi, and websites you visit.

Wi-Fi uses a wireless internet connection from a nearby router in your home or business, while cellular data uses radio towers operated by mobile carriers like Verizon or AT&T. Both let you access the internet on your phone or device, but they work differently and have different speeds and coverage areas.

A phishing attack is a scam where criminals send fake emails, texts, or messages pretending to be from trusted companies to trick you into giving them your passwords or personal information. You can spot one by looking for suspicious links, urgent language, and emails from addresses that don't match the real company.

A strong password is long (at least 12 characters), uses a mix of uppercase letters, lowercase letters, numbers, and symbols, and avoids common words or personal information. The harder it is to guess or crack, the stronger the password.
