Wi-Fi (Wireless Fidelity) is a technology that allows electronic devices to connect to a local area network (LAN) wirelessly, enabling internet access and communication without the need for physical cables. Developed in the late 1990s and standardized under the IEEE 802.11 family of protocols, Wi-Fi has become a ubiquitous standard for wireless networking in homes, offices, and public spaces.
One of the primary advantages of Wi-Fi is its flexibility and convenience, allowing users to move freely within the coverage area while maintaining a stable internet connection. Wi-Fi networks can be easily set up and scaled, making them suitable for a wide range of environments—from small residential setups to large enterprise networks.
