HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) are protocols used for transmitting data between a web client (e.g. web browser) and a web server over the internet. HTTP is the foundation of data communication for the World Wide Web, facilitating the retrieval and display of web pages, documents, and multimedia content. HTTPS is a secure version of HTTP that incorporates encryption (SSL/TLS) to protect the confidentiality, integrity, and authenticity of data exchanged between the client and server, preventing eavesdropping, tampering, or interception by unauthorized parties.
