What is Wi-Fi and how does it work?
Wi-Fi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. It works by transmitting data through radio waves at a specific frequency, typically 2.4 gigahertz (GHz) or 5 GHz. This allows devices such as laptops, smartphones, and tablets to connect to a network and access the internet, share files, and communicate with other devices.
Wi-Fi uses a technology called IEEE 802.11, which is a set of standards for wireless local area networks (WLANs). When a device connects to a Wi-Fi network, it sends a request to the router, which is the device that provides access to the network. The router then authenticates the device and assigns it an IP address, allowing it to access the internet and communicate with other devices on the network.
