**What does the acronym HTTP/2 signify in web technology?**
The acronym HTTP/2 signifies the second major version of the Hypertext Transfer Protocol, which is used for transmitting data on the web. Introduced to improve performance and efficiency, HTTP/2 brings enhancements like multiplexing, which allows multiple requests and responses to be sent simultaneously over a single connection, significantly reducing latency. It also supports header compression and prioritization of requests, improving loading times and user experience. This version is designed to address the limitations of the previous HTTP/1.1 and is widely supported by modern web browsers and servers.
