Understanding the difference between the internet and Wi-Fi can help users navigate the complex world of online connectivity and make informed decisions about their networking needs.
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) wants to connect to a Wi-Fi network, it sends a request to the network’s router, which is a device that connects to the internet and manages the flow of data. The router then sends a signal back to the device, which allows it to connect to the network. Once connected, the device can communicate with the router and access the internet or other devices on the network. Wi-Fi uses a specific frequency of radio waves (typically 2.4 or 5 gigahertz) to transmit data, and devices must be configured to use the same frequency in order to communicate with each other.
The range and speed of Wi-Fi connections depend on various factors, including the strength of the signal, the type of router and devices being used, and the amount of interference from other devices. In general, Wi-Fi connections can be faster and more reliable than other types of wireless connections (such as cellular networks), but they can also be more susceptible to interference and security risks.
