A Thin Client computer runs what looks like a full Windows NT 4.0 operating system on each Client installed in a factory. This is accomplished by having a powerful server running a version of Microsoft’s NT 4.0 designed for Thin Clients, NT Terminal Server 4.0. This version of Windows allows multiple users to log in and establish a full Windows session running on the server. Each user gets a dedicated share of memory, some slices of CPU time, and access to the server’s disks and applications.
