What is Wi-Fi (Wireless Fidelity)?

Wi-Fi, short for "Wireless Fidelity," is a technology that provides wireless access to the internet and local network resources. It uses radio waves to establish a network connection between devices, such as computers, smartphones, and routers, without the need for physical cables. Wi-Fi allows users to connect to the internet and communicate with other devices within a certain range of a wireless access point or router.

It has become ubiquitous in homes, businesses, public spaces, and various industries, offering the convenience of wireless connectivity for a wide range of devices and applications, from internet browsing and email to streaming media and smart home automation.
