LiFi, or Light Fidelity, is a wireless technology that uses light to transmit data. It is similar to Wi-Fi, but instead of using radio waves, LiFi uses visible light. This makes LiFi much faster than Wi-Fi, with speeds of up to 100 gigabits per second (Gbps) possible. LiFi works by using LEDs to modulate the light intensity. The LEDs are turned on and off rapidly, and the sequence of on and off signals represents the data being transmitted. A photodetector at the receiving end detects the changes in light intensity and converts them back into data. LiFi has a number of advantages over Wi-Fi. It is much faster, and it is also more secure, as light cannot penetrate walls. LiFi is also less susceptible to interference from other devices, such as microwaves and cordless phones. However, LiFi also has some disadvantages. It has a shorter range than Wi-Fi, and it does not work well in bright sunlight. LiFi also requires a direct line of sight between the transmitter and receiver. Application

Wi-Fi is a wireless technology that uses radio waves to connect devices to the internet. It is one of the most popular wireless technologies in the world, and it is used in a wide variety of devices, including smartphones, laptops, tablets, TVs, and smart home appliances. Wi-Fi works by transmitting data packets over radio waves. These data packets are made up of bits, which are the basic units of information in computing. The Wi-Fi router in your home or office converts the data packets from your devices into radio waves and transmits them through the air. The Wi-Fi adapter in your device then receives the radio waves and converts them back into data packets. Wi-Fi uses two different radio frequency bands: 2.4 GHz and 5 GHz. The 2.4 GHz band is a lower frequency band that has a longer range, but it is also more susceptible to interference from other devices, such as microwave ovens and cordless phones. The 5 GHz band is a higher frequency band that has a shorter range, but it is less
