Wi-Fi
Wi-Fi is a family of wireless network protocols based on the IEEE 802.11 standards, enabling devices to connect to a local area network (LAN) and access the internet without physical cables. It operates in the 2.4 GHz and 5 GHz radio frequency bands, providing high-speed data transmission over short to medium distances. Wi-Fi networks are commonly used in homes, offices, public spaces, and IoT devices for wireless connectivity.
Developers should learn about Wi-Fi networks when building applications that require wireless connectivity, such as mobile apps, IoT systems, or network-dependent software, to ensure reliable communication and handle network-related issues like latency or security. Understanding Wi-Fi is crucial for implementing features like offline mode, real-time data sync, or location-based services that rely on network availability. It's also essential for troubleshooting connectivity problems in deployed applications and optimizing performance in wireless environments.
