The surface Web (also known as the visible Web or indexable Web) is that portion of the World Wide Web that is indexed by conventional search engines. The part of the Web that is not reachable this way is called the deep Web. Search engines construct a database of the Web by using programs called spiders or Web crawlers that begin with a list of known Web pages. The spider gets a copy of each page and indexes it, storing useful information that will let the page be quickly retrieved again later. Any hyperlinks to new pages are added to the list of pages to be crawled. Eventually all reachable pages are indexed, unless the spider runs out of time or disk space. The collection of reachable pages defines the surface Web. For various reasons (e.g., the Robots Exclusion Standard, links generated by JavaScript and Flash, password-protection) some pages can not be reached by the spider. These 'invisible' pages are referred to as the deep Web. A recent study queried the Google, MSN, Yahoo!, and Ask Jeeves search engines with search terms from 75 different languages and determined that there were over 11.5 billion web pages in the publicly indexable Web as of January 2005. As of June 2008, the indexed web contains at least 63 billion pages. From Wikipedia under the

Answered by shirley_corsini - Thu Jul 13 12:28:23 2006 What web site can I find out what temperature it is at different altitudes? Q. I'm not asking about land elevation, I'm asking about finding out temperatures above the surface (above ground level). Asked by unknown - Thu Aug 24 19:23:09 2006 - - 5 Answers - 2 Comments A. All aircraft weather sites have charts that give you specific temperatures at various altitudes for different times of the day. It can be mind numbing if you cannot decipher it. A good rule of thumb small aircraft pilots use is 2 degrees per thousand. If the ground temp is 80 degrees then at 10,000 feet above ground level it would be 60 degrees. 80- (2x 10) The real rates are wet and dry adiabatic lapse rates. These consider the amount of moisture in the air and you can calculate the proper temp from them. It does get a little complicated since the real rates start from sea level to cloud height and then up. However to find a close temp the 2 degrees per thousand is a good average.

Q. I would like my web cam detect dirt/markings on a white surface(specifically white board)... Is this possible? Just like the concept of a surveillance camera... only it detects markings...
