Wi-Fi, short for Wireless Fidelity, refers to a technology that allows devices to connect to a local area network (LAN) using radio waves. It enables wireless communication between devices such as computers, smartphones, tablets, and routers, allowing them to access the internet and share data without physical connections. Wi-Fi operates on various frequency bands, primarily 2.4 GHz and 5 GHz, and adheres to the IEEE 802.11 standards, which define the specifications for wireless networking. The technology has become ubiquitous in homes, businesses, and public spaces, facilitating mobile connectivity and expanding access to the internet without the constraints of wired connections. Wi-Fi networks can be secured through encryption protocols, such as WPA (Wi-Fi Protected Access), to protect users‘ data and prevent unauthorized access.
