Quel est le nom de l’élément d’URL présent sur chaque page sauf la page d'accueil ?

The correct answer is Slug. A slug is the part of a URL that identifies a specific page on a website, typically appearing after the domain name and often reflecting the page's title or content. For example, in example.com/blog/my-awesome-post, my-awesome-post is the slug. The homepage usually doesn't have a slug because it's the root of the domain. A subdomain (e.g., blog.example.com) is a separate section of a website, not an element within a page's URL path. A TLD (Top-Level Domain, e.g., .com, .org) is the last segment of a domain name. A protocol (e.g., https://) specifies how data is transferred over a network. These options are fundamental parts of a URL but do not serve the specific function of identifying individual pages beyond the homepage in the URL path.
