Software used to access resources on the Internet. The Mosaic project has been conducted by the National Center for Supercomputing Applications (NCSA) in Illinois to provide a single front-end or user interface to many information services. The goal is to present the query to, and results from, each of these different information resources in a similar way to minimize the number of “systems” one must be familiar with to successfully navigate the Internet. Mosaic relies on the existence of servers; it does not serve information of its own. Mosaic client software exists for X Windows, Macintosh, and Microsoft Windows. Computers must be connected to the Internet to use Mosaic.
