The Google cache
The Google cache
A cache (pronounced cash) is a storage subject for computer files.Google maintains an enormous cache of Web pages. Dont confuse thecache with Googles Web index. Actually, for practical purposes, itdoesnt matter whether you confuse them or not, but they aredifferent.
The index is a database of Web page content, stripped of itsformatting. The cache contains the pages themselves. By and large,clicking the Cached link provides a quicker display of the targetpage because youre getting it from Googles computer instead of fromthe Internet at large.
So why would you ever not use the Cached link instead of the mainpage title link? Mainly because the cached page is not necessarilyup-to-the-minute, especially with pages that convert frequently(such as Weblogs and news sites). If you view the cached version ofa page that you know changes frequently and is dated, such as thefront page of a newspaper site, you can see that Googles cache is aday or more behind. For users without high-speed Internet access,its more convenient to exertion from the cache when looking for abig page (about 50K or so) that doesnt change much. You might alsouse the Cached link if the page title link refuses to display thepage for some reason.
The cache link comes in handy when you want to take a brief tripback in time, to view a Web page that you know has changed or hasbeen taken away. Once, David Letterman, on his late-night show,complained that the CBS site displayed a video of Lettermans rival,Jay Leno. Lettermans show is taped in the afternoon, and by thetime the show airy CBS had removed the offending image. Manypeople, including myself, wanted to preserve the amusing gaffe, andwe did so by calling up the old page in Googles cache.
