WI-FI

Wi-Fi is a technology that allows devices like computers, smartphones, and tablets to connect to the internet without using cables.

Here's how it works in simple terms:

Wireless Connection: Wi-Fi uses radio waves to transmit data between devices and a router, which is connected to the internet via a physical connection like a cable.

How It Works:

When you want to access the internet, your device sends a request to the router.

The router receives this request and forwards it to the internet through its wired connection.

The internet sends the requested data back to the router, which then broadcasts it to your device via Wi-Fi.

Frequencies Used: Wi-Fi operates on different frequencies, commonly 2.4 GHz and 5 GHz. The 2.4 GHz frequency has a longer range but slower speeds, while the 5 GHz frequency offers faster speeds but over a shorter distance.

Benefits: Wi-Fi provides flexibility and convenience, allowing you to move around with your devices while staying connected to the internet.

In essence, Wi-Fi is like a radio system that lets devices communicate with each other and the internet wirelessly.
