Active Server Pages.  ASP is Microsoft's server-side scripting technology.  An Active Server Page has an .asp extension and it mixes HTML and scripting code that can be written in VBScript or JScript.  ASP is distributed with Microsoft's IIS web server, so most host using IIS will also offer ASP for dynamic web programming.  ASP.NET is the next version of ASP.  Other popular server-side scripting languages are Perl, PHP, ColdFusion, TCL, Python, and JSP.
