Final answer:
A homepage is the starting point of a website, designed to provide an overview and guide users to various sections of the site.
Step-by-step explanation:
A(n) homepage is the introductory page for a Web site, and all other Web pages for that site are usually accessible from this page via links. The homepage serves as the starting point of a website and often contains a navigation menu that guides users to other sections of the site. It is designed to provide an overview of what the website offers and may also feature important announcements, featured content, and direct access to frequently sought information. In this context, 'index page,' 'landing page,' and 'portal page' can have specific meanings that differ from a homepage. For example, a landing page might be designed for marketing purposes and focus on a specific campaign or product, whereas a portal page may aggregate content from various sources, or serve as a gateway to a suite of related services or websites.
