(Internet Information Services) Microsoft's Web server. Formerly "Internet Information Server," IIS adds HTTP server capability to the server versions of Windows and various client versions, including Windows XP Professional, Vista, 7 and 8. See Web server, HTTP server and Smooth Streaming.
Usually this would be a server installed with Microsoft's Internet Information Services (IIS), although Sun has a product called Chili!Soft ASP which enables ASP to run on other non-Microsoft servers such as Apache, Red Hat, and others.
Even though the script for an ASP page can be written in VB or Java, the files are saved as ".asp" files, which means that the Microsoft Internet Information Server (IIS) should be configured with the ASP feature.
The Official Microsoft IIS PHP community offers an entire library of discussion threads covering all aspects of PHP programming for websites that are running on Microsoft IIS.
Hosts that haven't added the ASP feature to IIS will not be capable of running ".asp" pages.
Even Pentium IIs are fast becoming ancient history.
