What Is Wi-Fi?

Wi-Fi is a wireless technology that allows devices to connect to the internet or communicate with each other without using physical cables. It uses radio signals to send and receive data between devices and a Wi-Fi router.

How Does Wi-Fi Work?

Wi-Fi works by sending data through radio waves:

  1. Your router connects to the internet.
  2. The router sends wireless signals.
  3. Your device detects the Wi-Fi signal.
  4. The device connects to the network using a password.
  5. Data moves between your device and the router wirelessly.

In simple words: Wi-Fi lets your devices access the internet without needing an Ethernet cable.
