๐ก Quick Study Guide: Understanding WiFi
- ๐ก WiFi stands for "Wireless Fidelity." It's a technology that lets devices connect to the internet or to each other without needing physical cables.
- ๐ถ How it Works: WiFi uses invisible radio waves to send information between devices, just like a radio or TV uses radio waves to broadcast shows.
- ๐ Router: This is the main device in your home or school that creates the WiFi signal. It's like a central hub for your wireless network.
- ๐ป Devices: Laptops, smartphones, ๐ tablets, smart TVs, and game consoles can all connect to WiFi.
- ๐ Security: WiFi networks are often protected with passwords to keep your information safe and prevent unauthorized access. This is called encryption.
- ๐ Internet Connection: While WiFi connects your devices wirelessly, the router still needs to be connected to the internet (usually via a cable from your Internet Service Provider, or ISP) to give you access to websites and online services.
- โก Speed: The speed of your WiFi depends on many things, like your internet plan, how far you are from the router, and how many devices are using the network.
