A Uniform Resource Identifier (URI) is like an address on the internet. It helps you find webpages, websites, and other resources on the internet. Just like you need an address and zip code to find someone's house, a URI helps computers and other Internet users find the exact page they are looking for. A URI might include a website's name (like "google.com"), and a page's name (like "sports"). It might also include other information, like what kind of website it is (like "edu" for educational websites).
