HTTP 1 VS HTTP 2 VS HTTP3

Features	Http1.1	Http2
❇️Multiplexing:	🎯 HTTP/2: Supports multiplexing, allowing multiple requests and responses to be sent and received on the same connection simultaneously. This significantly improves performance and reduces latency, as resources can be loaded in parallel.	🎯 HTTP/2: Supports multiplexing, allowing multiple requests and responses to be sent and received on the same connection simultaneously. This significantly improves performance and reduces latency, as resources can be loaded in parallel.
❇️Header Compression:	🎯 HTTP/1.1: Headers are sent with each request and response and are not compressed, leading to additional overhead, especially for requests with many small resources.	🎯 HTTP/2: Introduces header compression, which reduces the overhead associated with sending headers, resulting in faster communication between the client and server.
❇️Binary Protocol:	🎯 HTTP/1.1: Uses plain text for communication between the client and server.	🎯 HTTP/2: Introduces a binary protocol, which is more efficient for both parsing and transmission. This results in lower overhead and improved performance.
❇️Connection Management:	🎯 HTTP/1.1: Requires multiple connections for parallelism, which can lead to higher resource usage on both the client and server.	HTTP/2: Uses a single, multiplexed connection, reducing the need for multiple connections and improving resource utilization.

HTTP/2 offers significant performance improvements over HTTP/1.1 by introducing features such as multiplexing, header compression, server push, and a binary protocol. These improvements result in faster loading times, reduced latency, and better resource utilization, making HTTP/2 the preferred choice for modern web applications.
