what is iis

IIS stands for Internet Information Services, which is a flexible, general-purpose web server created by Microsoft for use with the Windows NT family. It supports various protocols for communication and data exchange with remote clients or computers, such as HTTP, HTTPS, FTP, FTPS, SMTP, and NNTP. IIS can be used to host, deploy, and manage web applications using technologies such as ASP.NET and PHP. It is commonly used to host ASP.NET web applications and static websites, but it can also be used as an FTP server, host WCF services, and be extended to host web applications built on other platforms such as PHP. IIS allows web applications to fully leverage the powerful features and extensibility of ASP.NET 2.0.
