What does Wireless Fidelity (Wi-Fi) utilize to enable data exchange between devices?

Wireless Fidelity, commonly known as Wi-Fi, utilizes radio waves or microwaves to facilitate data exchange between devices. This technology allows devices such as laptops, smartphones, and tablets to connect to the internet and communicate with each other without needing physical cables.

Wi-Fi operates within specific frequency bands, typically at 2.4 GHz and 5 GHz, which are suitable for high-speed data transmission over short to medium distances. The use of radio waves enables Wi-Fi to provide flexibility and mobility, allowing users to connect to networks from different locations within the coverage area, thereby enhancing usability and convenience.

While there are other forms of wireless communication such as infrared signals or Bluetooth technology, these are not utilized in Wi-Fi technology for data exchange. Fiber optic cables, on the other hand, are used for wired connections and are not related to Wi-Fi, reinforcing the fact that radio waves or microwaves are the correct means used by Wi-Fi to transmit data.
