“Document Type Definition”, or, for short, DTD.

There is not just one type of HTML, there are actually many: HTML 4.01 Strict, HTML 4.01 Transitional, XHTML 1.0 Strict, and many more. All these types of HTML are defined in their respective W3C specifications, but they are also defined in a machine-readable language specifying the legal structure, elements and attributes of a type of HTML.

Given its syntax, the DTD declaration is often called, for short, “Doctype”.

Mobile App.

A mobile app is an application, not a site.

It runs on a specific mobile operating system, such as Android, Windows Phone or iOS. Each mobile app must be downloaded and installed. By contrast, a mobile Web site is created for viewing on mobile device browsers. Mobile device browsers function similarly to desktop browsers, except they are designed for a much smaller screen size.
