Wi-Fi Full Form
Wi-Fi Stands for Wireless Fidelity. It is a technology that enables wireless communication between devices over a local area network (LAN). It uses radio waves to transmit and receive data, allowing devices such as computers, smartphones, tablets, and other Wi-Fi-enabled devices to connect to the internet or to each other without the need for physical cables. When a device, such as a smartphone, wants to connect to a Wi-Fi network, it sends out a broadcast message asking if any Wi-Fi networks are available. The Wi-Fi network, which is often provided by a router, responds to the device with its network name i.e., SSID (SSID stands for service set identifier), and security information, such as a password. Once the device has this information, it can connect to the network.
