What are the differences between HTTP and HTTPS, and why is HTTPS considered essential for secure web communication?

HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting data over the web, while HTTPS (HTTP Secure) is a secure version of HTTP that encrypts data using SSL/TLS protocols, ensuring confidentiality, integrity, and authenticity of communication. HTTPS is essential for protecting sensitive information, preventing eavesdropping, and building trust with users.
