What is WiFi and how does it work?
WiFi 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.
WiFi networks are typically set up using a wireless router, which is connected to a physical internet connection such as a cable or fiber optic connection. The router then broadcasts a wireless signal that can be detected by devices within range, allowing them to connect to the network and access the internet. WiFi networks can be secured using passwords and encryption to prevent unauthorized access.
