What is HTTP/HTTPS?

The protocol used for transferring web pages and data between browsers and servers, with HTTPS adding encryption.

HTTP (Hypertext Transfer Protocol) defines how messages are formatted and transmitted on the web. Methods include GET (retrieve), POST (submit), PUT (update), DELETE (remove). Status codes indicate outcomes (200 OK, 404 Not Found, 500 Server Error).

HTTPS adds TLS/SSL encryption, ensuring data confidentiality, integrity, and authentication via certificates. HTTP/2 and HTTP/3 improve performance with multiplexing and reduced latency.
