Wi-Fi, or wireless fidelity, is a technology that allows electronic devices to connect to the Internet or other networks wirelessly. It uses radio waves to transmit data between devices such as smartphones, laptops, tablets, and routers.
A Wi-Fi network consists of a router that connects to the Internet and wireless devices that connect to the router. The router acts as a hub, allowing devices to communicate with each other and the Internet. Wi-Fi networks can operate on different frequencies, with the most common being 2.4 GHz and 5 GHz.
Wi-Fi technology has become ubiquitous and is found in homes, businesses, public spaces, and other locations. It allows users to access the Internet and connect with other devices without the need for cables or wires. Wi-Fi is widely used for a variety of activities, including browsing the web, streaming video and music, gaming, and accessing cloud-based services.
