Which technology allows for wireless connections to a network?

Wi-Fi is the technology specifically designed to enable wireless connections to a network. It uses radio waves to transmit data between devices and a wireless router, allowing users to connect to the internet and local networks without the need for physical cables. This capability is essential for providing mobility and convenience, as devices can connect from various locations within the range of the Wi-Fi signal.

While other options like Ethernet and Fiber Optics are significant in networking, they are primarily wired technologies. Ethernet relies on cables for network connectivity, and Fiber Optics uses light signals through optical fibers, also necessitating physical connections. Bluetooth, while enabling short-range wireless connections, is typically used for connecting devices like headphones, keyboards, and peripherals rather than providing broader network access like Wi-Fi does. Thus, Wi-Fi stands out as the primary technology for wireless networking.
