Frequently Asked Questions
Q: What is the difference between PNG and JPG images?
A: JPG is best for photos (smaller file size, good quality). PNG is best for graphics/logos (supports transparent backgrounds). GIF is for simple animations.
Q: Why should I use HTTPS instead of HTTP?
A: HTTPS encrypts your data, making it safe from hackers. HTTP sends data unencrypted. Always look for HTTPS when entering passwords or payment info.
Q: What is a VPN and why would I use one?
A: VPN (Virtual Private Network) hides your real IP address and encrypts all internet traffic. Used for privacy, bypassing geo-blocking, or public WiFi security.
Q: What is the difference between URL and URI?
A: URL (web address) is a type of URI. URI is broader and includes any identifier. All URLs are URIs, but not all URIs are URLs.
