What is a wireframe?
by Gavin Wye
Found this description of what a wire frame is though it was quite nice.
It's from boagworld

"Fundamentally a wireframe is a tool for rapidly prototyping a website. They roughly approximate the layout, content and hierarchy of a web page as well as the relationship between pages. Effectively you are building a rough version of the site.
Wireframes don’t look attractive. They are not designed as such. Rather they give a sense of how things will be organised on your site. In many cases they lack colour and imagery, although there is no reason why they should. However, they do show visual hierarchy through layout, font size and shading."
