Code

There are several types of languages, and code systems, that are used commonly on the web, or were influential in the development of the web, a few of which are listed below (in alphabetical order):

1. ASCII: (American Standard Code for Information Interchange) is a character encoding based on the English alphabet.
2. C#: An object-oriented programming language developed by Microsoft as part of their .NET initiative.
3. CSS: (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in a markup language.
4. DHTML: (Dynamic HTML) is a method of creating interactive web sites by using a combination of static markup language HTML, a client-side scripting language (such as JavaScript), Cascading Style Sheets), and the Document Object Model.
5. GML: (Generalized Markup Language) developed in the 1960s by IBM's Charles Goldfarb, Edward Mosher and Raymond Lorie.
6. GML: (Geography Markup Language) is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet.
7. HEX: (hexadecimal) is a base-16 numeral system usually written using the symbols 0–9 and A–F or a–f.
8. HTML: (Hypertext Modeling Language) is the primary coding language used for documents on the Web. It is a subset of SGML.
9. Java: An object-oriented programming language developed in the early 1990s.
10. Javascript: Netscape's implementation of ECMAScript, a scripting programming language based on the concept of prototypes.
11. MathML: (Mathematical Markup Language) is an application of XML for representing mathematical symbols and formulae for the Web.
12. MusicXML: An open, XML-based music notation file format.
13. PHP: (PHP: Hypertext Preprocessor) is a scripted programming language mainly for developing server-side applications and dynamic web content, and software applications.
14. RDF: (Resource Description Framework) is a family of specifications for a metadata model that is often implemented as an application of XML.
15. RSS: A family of web feed formats, specified in XML and used for Web syndication. RSS can stand for several variations - Really Simple Syndication, Rich Site Summary, RDF Site Summary, or Real-time Simple Syndication.
16. SGML: (Standard Generalized Markup Language)is a metalanguage used to define markup languages for documents. SGML is a descendant of GML.
17. SVG: (Scalable Vector Graphics) is an XML markup language for describing two-dimensional static and animated vector graphics.
18. UTF-8: (8-bit Unicode Transformation Format) is a variable-length character encoding for Unicode which represents any universal character in the Unicode standard, yet is backwards compatible with ASCII.
19. XML: (Extensible HyperText Markup Language) is a markup language that has the same expressive possibilities as HTML, but a stricter syntax. Whereas HTML is an application of SGML, a very flexible markup language, XHTML is an application of XML, a more restrictive subset of SGML. •
