The Internet works by connecting computers and devices worldwide through a vast network of cables and wireless connections. Data is transferred over this network using protocols like TCP/IP. When you access a website, your device sends a request through this network to the server hosting the website; the server then responds by sending the data back to your device, allowing you to view the website.
