How does Wi-Fi differ from traditional internet connections?

Wi-Fi differs from traditional internet connections primarily because it provides a wireless method of communication. Unlike wired connections, which rely on physical cables to transmit data, Wi-Fi uses radio waves to enable devices to connect to the internet without the need for direct tethering. This characteristic allows users greater flexibility and convenience, as devices can connect from various locations within the range of the Wi-Fi signal without being physically connected to a router.

While other options mention aspects like the use of cables, specific uses like video streaming, or security measures, none accurately characterize the fundamental nature of Wi-Fi as a technology focused on wireless connectivity. The wireless aspect is what allows multiple devices to access the internet simultaneously and enables mobility, distinguishing it from traditional wired methods.
