Final answer:
A URL is the specific and unique address of a Web page found in the address bar of a browser. It includes the domain name but also contains additional information leading to a specific page or file.
Step-by-step explanation:
The URL of a Web page is an abbreviation for Uniform Resource Locator, which serves as the address of a Web page. Contrary to one of the provided options, the URL is not the same for each Web page on a website; each page has a unique URL. Therefore, not all the provided options are correct. The URL is indeed the address of the Web page and can generally be found in the address bar of a web browser. The domain name is a part of the URL, but the URL usually includes more details than just the domain name such as a specific path to a page or file on that domain.
