πŸ“š 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.
  • πŸ”’ HTTPS (Hypertext Transfer Protocol Secure): The secure version of HTTP, using SSL/TLS to encrypt communication, preventing eavesdropping and tampering.
  • πŸ”‘ 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.
  • πŸ›‘οΈ Port 443: The default port for HTTPS.
  • πŸ“ 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.
  • πŸ’Έ Cost: HTTPS requires obtaining and maintaining SSL/TLS certificates.
