💡 What is WiFi?

🏠 WiFi is a way for your devices, like tablets and phones, to connect to the internet using special radio waves.
📡 Think of it like a invisible rope that connects your device to a box called a 'router' in your house or school.
🌐 Once connected to the router, your device can go online and visit websites or watch videos.
📍 WiFi usually works best when you are close to the router, within a certain area like your home or a coffee shop.
💰 Often, using WiFi at home is part of your internet bill and doesn't cost extra to use on your devices.

📱 What is Cellular Data?

🌳 Cellular data is another way for your devices, especially smartphones, to connect to the internet when you are away from WiFi.
🗼 It uses signals from tall 'cell towers' that are spread out almost everywhere, like invisible bridges.
🌍 This means you can use the internet even when you're in a car, at the park, or visiting a friend's house far away from your WiFi.
💳 Using cellular data usually costs money, and you pay your phone company for how much you use, like buying minutes for a game.
📏 Cellular data coverage can vary; sometimes it's super fast, and other times it might be slower depending on where you are.
