HTTPS differs from HTTP because it

• A. Encrypts HTTP traffic with SSL or TLS using port 443.
• B. Uses UDP instead of TCP.
• C. Is faster than HTTP due to no encryption.
• D. Stores webpages offline.

Answer: (D)

HTTPS adds a security layer by using TLS/SSL to encrypt the entire HTTP conversation. This means your browser and the server perform a TLS handshake, exchange certificates, and then all request and response data is encrypted in transit. This prevents eavesdroppers from reading or tampering with the content and lets you verify you’re talking to the legitimate server. Because of this, HTTPS typically uses port 443 and runs over TCP. It is not faster than HTTP because of encryption; there is some overhead, though modern implementations minimize it. HTTPS does not inherently store pages offline; offline storage or caching is independent of whether the connection is secure or not.
