Web 1.0 was the first generation of the world wide web and allowed for one-way broadcasting of information from website owners. Web 2.0 focused on enabling collaboration and information sharing between users online through things like social media platforms and wikis. Web 3.0 extended on these social aspects and aimed to provide location-aware and moment-relevant experiences across multiple devices. Web 4.0, still in development, envisions a symbiotic relationship between humans and machines through technologies like ambient intelligence and mind-controlled interfaces. Each generation brought new interactive capabilities to the internet and how people engage with online information.
