Wi-Fi is a wireless networking technology that allows devices to connect to the internet or to other devices without the need for cables or wires. Wi-Fi operates using radio waves in the 2.4 GHz and/or 5 GHz frequency bands, and requires a Wi-Fi enabled device such as a smartphone, tablet, laptop, or desktop computer, as well as a Wi-Fi access point or router that is connected to the internet. Wi-Fi technology provides high-speed data transfer rates and enables multiple devices to be connected simultaneously, making it a popular and convenient option for home and business networking. Wi-Fi networks can be secured with passwords and encryption to protect data and prevent unauthorized access. Wi-Fi technology has become an essential part of modern computing and communication, enabling people to stay connected and productive from anywhere with a wireless network signal.
