Banner Ads
Those graphic advertisements that you see at the top of so many Web pages.
Cache
Your browser stores everything it reads on the user's hard disk. Every HTML page, every graphic. The next time it comes to pull down the same page, it uses the cached version, which is much faster - no need to download again via the Internet.
Frames
An HTML technique allowing Web site designers to display two or more pages in the same browser window. Most search engines do not index framed Web pages properly - they only index the text present in the NOFRAMES tag. Unless a Web page which uses frames contains relevant content in the NOFRAMES tag, it is unlikely to get a high search engine ranking.
