What is Wi-Fi?

Overview

Wi-Fi is a technology that allows electronic devices to connect to the internet without using physical cables. It works by using radio waves to send and receive data between a router and devices like smartphones, laptops, and tablets. This wireless connection is made possible through a series of standards set by the Institute of Electrical and Electronics Engineers (IEEE), which define how devices communicate over the air. When you connect to a Wi-Fi network, your device communicates with a router, which is connected to the internet. The router acts as a bridge, sending data to and from the internet while ensuring that the information reaches the correct device. For example, when you stream a video on your tablet, the router fetches the video data from the internet and transmits it wirelessly to your device, allowing you to watch it without any cables. Wi-Fi is important because it provides convenience and flexibility in how we access the internet. It allows multiple devices to connect to the internet simultaneously, making it easy for families or businesses to share a single internet connection. Without Wi-Fi, many of the devices we rely on daily, such as smart home devices or mobile phones, would not function as easily, limiting our ability to stay connected.
