How does Wi-Fi work?
Wi-Fi works by using radio waves to transmit data between devices. When a device, such as a laptop or smartphone, is connected to a Wi-Fi network, it sends a request to the network’s router to access the internet. The router then sends the requested data back to the device, using radio waves to transmit the information. The device receives the data and decodes it, allowing the user to access the internet, send emails, and perform other online activities.
The process of connecting to a Wi-Fi network involves several steps. First, the device searches for available networks and selects the one to connect to. The device then sends a request to the router to authenticate and connect to the network. Once connected, the device can send and receive data to and from the router, which acts as a bridge between the device and the internet. The router is typically connected to a physical internet connection, such as a cable or fiber optic line, which provides access to the wider internet.
