The acronym "WIFI" stands for "Wireless Fidelity." It is a technology that allows electronic devices to connect to a local area network (LAN) and the internet using radio waves. WIFI enables seamless communication between devices without the need for physical wires, enhancing user convenience and mobility. It is widely used in homes, offices, and public spaces for internet connectivity, accommodating multiple devices simultaneously. The technology has evolved through various standards, such as IEEE 802.11, each improving data transfer speeds and network reliability.
