HTTP (Hypertext Transfer Protocol) - HTTP is a client/server protocol for delivering hypertext material across an internet. HTTP is stateless: when a client makes multiple requests to a single HTTP server, each request is treated independently. HTTP servers do not remember the earlier requests. The stateless protocol allows HTTP servers to respond to requests quickly.

HTTPS (Hypertext Transfer Protocol - Secure) - A variant of HTTP for handling secure transactions. Browsers that support the URL access method, “https”, connect to HTTP servers using SSL. “https” is a unique protocol that is simply SSL underneath HTTP. Use “https://” for HTTP URLs with SSL and “http://” for HTTP URLs without SSL. The default “https” port number is 443.

Hyperlink - An active cross-reference from one resource to another. The cross-reference is called active because it is presented in a medium which allows the reader to follow it, for example by mouse-clicking it.
