11. How HTTP works ? What is HTTP/2?

To answer the question, HTTP (Hypertext Transfer Protocol) is a protocol used to transmit data over the internet. It is the foundation of data communication for the World Wide Web.

When a user accesses a website, their web browser sends an HTTP request to the server hosting the website. The server then sends an HTTP response to the browser, which contains the requested data, such as HTML, CSS, JavaScript, and images.

HTTP/2 is an updated version of HTTP that aims to improve the performance of websites. It introduces several new features such as multiplexing, header compression, and server push. Multiplexing allows multiple requests and responses to be sent over a single connection, instead of multiple connections. Header compression reduces the size of the HTTP headers, which helps to reduce the amount of data sent over the network. Server push allows the server to send additional resources to the browser before the browser requests them, which can help to speed up page load times.

Overall, understanding how HTTP works and its latest version, HTTP/2, is crucial for FrontEnd engineers to optimize website performance and speed.
