Internet Information Services (IIS) is created by Microsoft to provide
Internet-based services to ASP.NET Web applications. It makes your computer to
work as a Web server and provides the functionality to develop and deploy Web
applications on the server. IIS handles the request and response cycle on the
Web server. It also offers the services of SMTP and FrontPage server
extensions. The SMTP is used to send emails and use FrontPage server extensions
to get the dynamic features of IIS, such as form handler.
