HTTP/2 is an updated version of the Hypertext Transfer Protocol, which is the foundation of data communication on the web. It was developed to improve the speed and efficiency of web browsing by allowing multiple requests and responses to be sent simultaneously over a single connection. This reduces the time it takes for web pages to load. One of the key features of HTTP/2 is its use of binary framing, which organizes data into smaller, manageable packets. This helps in reducing latency and improving overall performance, making it easier for websites to deliver content quickly and efficiently to users.
