The internet is a vast global network that connects billions of computers and devices, allowing them to share information with one another. It isn't controlled by any single company or country — instead, it's made up of countless smaller networks all linked together.
Data travels across the internet through a mix of physical infrastructure, including fiber-optic cables that run under oceans, cell towers, satellites, and Wi-Fi routers. Every device connected to the internet has a unique address, called an IP address, that helps route information to the right destination.
The World Wide Web, often just called 'the web,' is only one part of the internet. It refers specifically to websites and pages accessed through a browser, while the internet as a whole also carries email, video calls, online gaming, and countless other kinds of data.
