The term "wi-fi" signifies a wireless communication technology that allows devices to connect to the internet or communicate with each other over a radio signal. It enables devices like smartphones, laptops, and tablets to maintain network connectivity without the need for physical cables. Wi-fi operates using standards defined by the IEEE 802.11 protocols, which dictate the technical aspects of the wireless network, including frequency bands, security protocols, and signaling methods. The convenience and speed of Wi-fi have revolutionized how people access information and communicate in homes, offices, and public spaces.
