Website
A website is a collection of related web pages and associated files grouped under a shared domain or identity. The pages usually link to one another, often through a homepage, navigation menus, and internal links, so the site functions as one coherent resource rather than as isolated documents.
This concept is easy to blur with both web browser and web server. The browser is the software you use to view a site. The server is the machine or infrastructure that hosts and serves the site's files. The website is the thing in between: the actual body of pages, media, styles, and logic that the user is trying to access.
The distinction matters because it prevents a lot of sloppy diagnosis. If someone says "the website is down," the actual failure may live at the server or network layer. If someone says "open the website," what they really mean is "use the browser to request and display the site's pages."
Sites also vary in shape. Some are many-page collections with stable URLs for each section. Others are single-page applications that update dynamically while keeping the interface inside one shell. The underlying concept is still the same: one organized web resource experienced as a whole.
