Wi-Fi
Wi-Fi is a wireless networking technology that allows devices to connect to the internet and communicate with each other over radio waves, typically using the IEEE 802.11 family of standards. It enables local area networking (LAN) without physical cables, operating in the 2.4 GHz and 5 GHz frequency bands, and is widely used in homes, offices, and public spaces for internet access and device connectivity.
Developers should learn Wi-Fi for building applications that rely on wireless connectivity, such as IoT devices, mobile apps, and network-dependent software. It's essential for implementing features like real-time data synchronization, remote control, and location-based services, and is critical in environments where wired connections are impractical or for enhancing user mobility.
