Multiple Choice Questions on HTTP and HTTPS for AP Computer Science A

📚 Quick Study Guide

• 🌐 HTTP (Hypertext Transfer Protocol): The foundation of data communication on the web. It's a protocol for fetching resources such as HTML documents.
• 🔒 HTTPS (Hypertext Transfer Protocol Secure): The secure version of HTTP, using SSL/TLS to encrypt communication, preventing eavesdropping and tampering.
• 🔑 SSL/TLS: Protocols that provide cryptographic security for communication over a network. SSL is the older protocol, while TLS is its successor.
• 🤝 Port 80: The default port for HTTP.
• 🛡️ Port 443: The default port for HTTPS.
• 📝 Key Difference: HTTPS provides encryption, authentication, and integrity, while HTTP does not. This ensures data is transmitted securely between the browser and the web server.
• 💸 Cost: HTTPS requires obtaining and maintaining SSL/TLS certificates.
