One new technology that has been gaining popularity recently is Li-Fi (Light Fidelity). Li-Fi is a wireless communication technology that uses light to transmit data. It is similar to Wi-Fi, but instead of using radio waves to transmit data, Li-Fi uses light waves.

Li-Fi technology uses LED light bulbs to transmit data. The LED bulbs can be turned on and off at high speeds, which is not visible to the human eye. The on/off patterns of the LED bulbs are then detected by a receiver, which is connected to a device such as a computer or a smartphone. This allows data to be transmitted wirelessly using light waves.
