Wi-Fi is a wireless networking technology that uses radio waves to transmit data at high speeds.
Most modern devices, such as phones, computers, and IoT gadgets, have built-in wireless adapters that allow them to connect to wireless access points (WAP). These access points serve as gateways, facilitating untethered internet access and device-to-device communication.
Users rely on Wi-Fi to wirelessly transfer files, stream content, play games, and run business applications in a local environment.
