A Website, or Host is the entire collection of related web pages under a single domain name. The collection will include the homepage, internal pages, navigation, etc.
We can think of a Website Host as a book.
Example: https://www.activecomply.com/
Website Pages, on the other hand, are individual documents within the website, each with its own unique URL. They will serve specific purposes, such as the homepage, product or service pages, blog posts, etc.
We can think of Website Pages as the individual pages within a book.
