Types of Web Servers
There are typically 2 operating systems that web sites are hosted on: Windows or Linux.
Windows IIS (Internet Information Services) is the typical platform for Active Server Pages, or ASP pages. You’ll see a wide variety of file extensions hosted on IIS servers: .ASP, .ASPX, .HTM, .HTML, .PHP, etc.
Linux with Apache is the typical platform for Hypertext Preprocessor pages, or PHP pages. You’ll see the following common files running on an Apache server: .PHP, .HTM, .JSP (Java server pages), and .HTML.
Keep in mind that the operating system doesn’t always limit the type of web server software running on the server. You can certainly have a Windows operating system running the Apache webserver. You cannot however have a Linux machine running Internet Information Services (IIS). The same can be said for programming platforms such as PHP, ASP, Ruby, JSP, etc. You can run PHP pages on a Windows or Apache server easily. Servers such as Apache’s Tomcat also have their place.
There are a lot of other servers out there, but we’ll be focusing on the platforms that are popular for website owners, and those platforms are IIS and Apache.
