COMPUTER FUNDAMENTALS

Detailed explanation-1: -Wi-Fi uses radio waves to transmit information between your device and a router via frequencies. Two radio-wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz. What does that mean, though? Well, a hertz is just a measurement of frequency.

Detailed explanation-2: -WiFi works off of the same principal as other wireless devices-it uses radio frequencies to send signals between devices. The radio frequencies are completely different say from walky talkies, car radios, cell phones, and weather radios.

Detailed explanation-3: -4) WiFi Uses Radio Waves uses a wireless adapter to translate data into a radio signal and transmit that signal using an antenna. Those radio waves emanate outwards from the antenna and are received by your wireless router.

Detailed explanation-4: -Wi-Fi is the radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use. The device transmits a radio signal back to the router, which connects to the internet by wire or cable.

Detailed explanation-5: -Wi-Fi uses radio waves with a faster frequency than AM and FM radio. While AM radio is measured in kilohertz and FM radio in megahertz, Wi-Fi is measured in gigahertz. This measurement is why you see Wi-Fi connections labeled as 2.4 GHz and 5 GHz-which are a generalization of frequency ranges.
