Microsoft's Internet Information Services (IIS) is a flexible, general-purpose web server that delivers HTML pages or files requested on Windows computers.

Client workstations located remotely can submit queries to an IIS web server, which will then return the appropriate response. Using this foundational functionality, Web servers can share and distribute data across LANs, such as corporate intranets, and WANs, such as the Internet.

A web server can provide users with information in numerous formats, including HTML-coded static web pages, file downloads and uploads, text documents, and image files.
