4.1. Browsing contexts

A browsing context is a collection of one or more Document objects,  
and one or more views.

At any one time, one of the Documents in a browsing context is the  
active document. The collection of Documents is the browsing  
context's session history.

A view is a user agent interface tied to a particular media used for  
the presentation of Document objects in some media. A view may be  
interactive. Each view is represented by an AbstractView object. Each  
view belongs to a browsing context. [DOM2VIEWS]


Note: A typical Web browser has one obvious view per browsing  
context: the browser's window (screen media). If a page is printed,  
however, a second view becomes evident, that of the print media. The  
two views always share the same underlying Document, but they have a  
different presentation of that document. A speech browser also  
establishes a browsing context, one with a view in the speech media.


4.1.1. Nested browsing contexts

Certain elements (for example, iframe elements) can instantiate  
further browsing contexts. These are called nested browsing contexts.  
If a browsing context P has an element in one of its Documents D that  
nests another browsing context C inside it, then P is said to be the  
parent browsing context of C, C is said to be a child browsing  
context of P, and C is said to be nested through D.
