ASP may refer to any of the following:
1. Short for Active Server Page, an ASP page is a dynamically created web page that ends with a .ASP extension that utilizes ActiveX scripting, usually VBScript or JScript code. The .aspx extension is used for Web pages that use Microsoft's ASP.NET. These pages are called "Web Forms," and often contain (X)HTML code, and ASP.NET code.
2. Short for application service provider, ASP is a third-party provider that handles and distributes your business data and customer data.
3. Short for authorized service provider, ASP is a location that is authorized by the computer manufacturer as a place to service your computer.
4. Short for AppleTalk session protocol, ASP is a portion of the AppleTalk protocol that receives responses from commands sent over AppleTalk.
5. Answer set programming, also known as ASP, is a declarative programming paradigm that is used to solve NP-hard computing problems. It reduces extremely difficult problems into simplified, stable problem models, and attempts to solve them using specialized programs known as answer set solvers. An example of an answer set programming language is AnsProlog, which is a specialized version of Prolog that avoids infinite loops when solving extremely difficult problems.
