Wi-Fi is essentially a wireless way to connect your devices to the internet. Imagine it as an invisible web of radio waves that lets your laptop, smartphone, tablet, and other gadgets communicate with the internet through a device called a wireless router.
Here's a breakdown of how it works:
Wireless Router: This box acts as a translator. It receives the internet signal from your internet service provider (ISP) usually through a cable, and then converts it into radio waves. These radio waves are what we call Wi-Fi.
Radio Waves: These waves travel through the air, similar to radio or TV signals, and reach your Wi-Fi-enabled devices like laptops and phones.
Device: Your device picks up the Wi-Fi signal, translates it back into data it can understand, and allows you to access the internet.
This way, you can browse websites, stream videos, download files, and more, all without being tethered to a cable.
