What is Wi-Fi and how does it allow devices to connect wirelessly?

Question

Wi-Fi is one of the most widely used technologies today. It allows devices to connect to the Internet without cables. But how does Wi-Fi actually work?

Answer 1

Wi-Fi is a wireless communication technology that allows devices to connect to the Internet using radio waves. A Wi-Fi router sends and receives these radio signals. When you connect your phone or laptop to Wi-Fi, your device communicates with the router, which then forwards your data to the Internet through a broadband connection.

Wi-Fi works under standards such as IEEE 802.11.

Answer 2

Different Wi-Fi bands like 2.4 GHz and 5 GHz offer varying speeds and range. Wi-Fi is secure when protected with strong passwords and encryption methods like WPA2 or WPA3. For Technology Basics GK, remember: Wi-Fi = wireless network + uses radio waves + connects devices without cables.
