How is a "page" represented in Sitecore?

In Sitecore, a "page" is represented as an item in the content tree with templates. This means that each page is not merely a static entity but is instead a structured content item that adheres to defined templates. These templates dictate the fields and settings associated with each page, such as title, content, layout, and additional metadata.

This structure allows for flexibility and scalability, enabling developers and content editors to create, manage, and deploy content easily. By using templates, Sitecore can enforce consistency across similar types of pages, while still allowing for individual customization as needed.

The other responses focus on different aspects of web content management. While a URL that points to the content identifies where a page can be accessed, it does not define how the page itself is constructed within Sitecore. A visual component on the website relates more to the presentation layer rather than the underlying structure of content in Sitecore. Lastly, describing a page as a document stored in the database abstracts it from the Sitecore content item model, which is primarily based on the item and template paradigm.
