Peer-to-peer computing. A process where two computers communicate directly without the mediation of a server. One of the best examples of P2P is the Napster service.
In a Web context, a page is normally a Webpage, the entire set of content, navigation, and graphics downloaded to the browser when the reader clicks a link or enters a URL. A page may be made up of a number of screens and may thus require scrolling to move up and down it. Pages should only scroll vertically, not horizontally.
A small software program that counts the number of visits a Webpage receives and publishes that number on the page. Using a page counter is seen as amateur and is not recommended.
