A server computer is provided for representing and navigating the connectivity of Web pages. The Web pages include links to other Web pages. The links and Web page s have associated names (URLs). The names of the Web pages are sorted in a memory of the connectivity server. The sorted names are delta encoded while periodically storing full names as checkpoints in the memory. Each delta encoded name and checkpoint has a unique identification. A list of pairs of identifications representing existent links is sorted twice, first according to the first identification of each pair to produce an inlist, and second according to the second identification of each pair to produce an outlist. An array of elements is stored in the memory, there is one array element for each Web page. Each element includes a first pointer to one of the checkpoints, a second pointer to an associated inlist of the Web page, and a third pointer to an associated outlist of the Web page. The array is indexed by a particular identification to locate connected Web pages.
