Scripts are often embedded in Web pages, either in an HTML page (on the client side) or in an ASP page (on the server side). In the case of a script embedded in an HTML page, the engine component that interprets and runs the script code is loaded by the Web browser, such as Internet Explorer. In the case of a script embedded in an ASP page, the engine that interprets and runs the script code is built into Internet Information Services (IIS).
Windows Script Host executes scripts that exist outside an HTML or ASP page and that stand on their own as text files
