Web development
Web development incorporates all areas of creating a Web site for the World Wide Web. This includes Web design (graphic design, XHTML, CSS, usability and semantics), programming, server administration, content management, marketing, testing and deployment. The term can also specifially be used to refer to the "back end", that is, programming and server administration. There are usually more than one member that works on a given Web Development team, each specialising in his or her own field.

Web Servers and HTTP Daemons
Web servers run on an operating system and serve HTTP requests from clients, usually a Web browser. In UNIX, a daemon is a type of process that runs in the background, under control of the OS, and is usually launched at startup and ran constantly. Akin to this is "services" in Microsoft Windows.

Server-Side Scripting
Server-side scripting is the scripting of the web server to respond dynamically to HTTP requests. Being the opposite of static, this means that an HTML page is not simply served but processed by the scripting engine before the result being sent to the client. Quite often a scripting language connects to a database and fills an HTML template with content.
