Virtual User Interface Software

Virtual user interface (VUI) software runs on servers and creates within the operating system a user interface that is virtualized for distribution to a nonnative environment. Terminal emulators, on the other hand, are not included in this category because they run on clients rather than servers. Representative vendors and products include the following:

• Citrix (MetaFrame)
• Microsoft (Terminal Services)
• Sun Microsystems (Sun Secure Global Desktop Software)
• X-Windows (many vendors)
