A website (alternatively, web site or Web site) is a collection of Web pages, images, videos or other digital assets that is hosted on one or several Web server(s), usually accessible via the Internet, cell phone or a LAN.
A Web page is a document, typically written in HTML, that is almost always accessible via HTTP, a protocol that transfers information from the Web server to display in the user's Web browser.
