The acronym DOM stands for Document Object Model. It is a programming interface that represents and interacts with objects in HTML and XML documents. The DOM allows developers to manipulate the structure, style, and content of web documents dynamically.

When a web page is loaded, the browser creates a DOM of the page, which acts as a bridge between the structure of the document and the programming languages used to manipulate it, primarily JavaScript. This model presents the document as a tree of objects, where each node represents part of the document, such as elements, attributes, text, and more. Through this model, developers can access and modify the content and structure of web pages programmatically, enabling dynamic and interactive user experiences.

The other options do not accurately capture the standard definition used in web development. "Data Object Model" and "Dynamic Object Model" are not recognized terms in this context, while "Document Output Model" does not fit the role defined by DOM within web technologies.
