Why HTTP is required?

HTTP (Hypertext Transfer Protocol) is essential because it facilitates communication between web clients (like browsers) and servers, enabling the retrieval of web pages and resources. It defines how messages are formatted and transmitted, and how web servers and browsers should respond to various requests. Without HTTP, the World Wide Web would not function, as there would be no standardized way for users to access and interact with online content. Additionally, it supports various features such as caching, cookies, and secure connections (HTTPS), enhancing the overall web experience.
