"Wi-Fi" stands for Wireless Fidelity, a technology that facilitates the wireless transmission of data over a network. It operates using radio waves that connect devices like computers, smartphones, and printers to a network without physical cables. Wi-Fi utilizes specific protocols, primarily those defined by the IEEE 802.11 standards, to maintain stable and secure connections. Typically, a wireless router acts as a central hub, allowing multiple devices to connect to the internet simultaneously while managing bandwidth effectively.
