What is the fastest internet technology?

Could you please enlighten me on the latest advancements in internet technology? Specifically, I'm curious to know what is currently considered the fastest internet technology available? Is it a new type of wireless connection, fiber optic cables, or perhaps something else entirely? Could you elaborate on its speed capabilities, the technology behind it, and any potential benefits it offers compared to existing solutions? I'm also interested in whether this technology is widely accessible or still in its early stages of deployment. Thank you for your insights!
