Step-by-step explanation:
The 4) WiFi Icon is used to display a list of available networks on a device. When you click or tap on this icon, typically found in the system tray or status bar of a device's operating system, it brings up a list where you can view all the wireless networks in range.
Each network's signal strength and security status are usually shown, and you may be prompted to enter a password if the network is secured.
