DOM stands for Document Object Model. In simplistic terms, the DOM
is a collection of objects that make up a document. Headings,
paragraphs, links, tables, forms, controls, etc, these are all
objects you might expect to make up a document of the web site
variety. Think of it as a sort of recipe. The various objects are
the ingredients that make up the page, which is the finished
delicacy. It is often a higherarchy, if you are interested in having
it broken down that far. Basically, a an edit box and a button might
be objects making up a form, which in turn is an object that is part
of a group of various objects that make up a page.

It depends on how the screen reader interacts with the browser,

with the DOM directly not with the on-screen presentation, but
when Jaws first came out it did not do this; it interacted
directly with the on-screen presentation as far as I can tell.
What exactly does VoiceOver do? If they interact with the DOM,
then it is still in a very rutamentary way. It cannot move by
element type (forward/backward by heading, list item, paragraph,
etc). In another message, Josh suggested that VoiceOver+up/down
arrow moves within the current column. Again, they must either be
using on-screen presentation to detect this or be reading the DOM
and the CSS.

I don't understand why you think this would be a problem with a
correctly authored webpage where content is separated from on-screen
presentation. HTML has no concept of columns; that should be a
styling
added by CSS. Maybe you're thinking of broken webpages that misuse
the
<table> element for for layout?
