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, providing high-speed data transmission in homes, offices, and public spaces. Wi-Fi is widely used for internet access, file sharing, and connecting IoT devices.
Developers should learn Wi-Fi for building applications that rely on wireless connectivity, such as mobile apps, IoT systems, and network-dependent software. It's essential for troubleshooting network issues, optimizing performance in wireless environments, and implementing secure communication protocols in distributed systems. Use cases include developing smart home devices, creating location-based services using Wi-Fi positioning, and ensuring robust connectivity in enterprise applications.
