Wi-Fi

Wi-Fi stands for "Wireless Fidelity" and it is a way to connect electronic devices like computers, tablets and phones to the internet, without needing any wires. Instead, it uses radio waves to send information back and forth, like a TV or radio. When you want to connect to the internet, your device looks for a wi-fi connection and then uses that connection to send or receive data. With wi-fi, you can stay connected without ever having to plug in a wire.
