Windows NT is the flagship product of Microsoft and is a very popular OS for workstations and servers. NT is a graphical OS that simplifies many tasks that are difficult to accomplish on a Unix Platform.
NT comes in two variations, Server and Workstation. NT Workstation is designed for business applications with less users that require a stable environment and faster performance for their applications. The more popular NT server variant is used as a server in organizations with a large number of users. Together with Internet Information Server, the server is widely used as a web server and is often used to integrate an intranet into the internet. The recent Windows 2000 is referred to as Windows NT 5.0.
