A user can retrieve and use software simply by navigating with a web browser. Formerly static information can be paired with portable software for interpreting and using the information. Instead of just providing some data for a spreadsheet, for example, a web document might contain a fully functional spreadsheet application embedded within it that allows users to view and manipulate the information.
