What is Wi-Fi?

A: Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smartphones, wearables, and XR/VR HMDs), and other devices (TVs, printers, cameras) to connect, both to each other for local functionality, such as screencast, and to the internet for cloud services. Wi-Fi allows all these devices, and many more, to exchange information over the internet, creating a network.
