This is an HTML technique which allows a webmaster to display two or more separate web pages within a single browser screen. Sites using frames are quite problematic for search engines to crawl and may not be indexed properly. Search engines often will only index pages linked within the <NOFRAMES> tag. If your site utilizes frames, it is highly recommended that you build a site map for your website, and link to it from within your <NOFRAMES> tag.
