HTML
HTML (Hypertext Markup Language) is the set of markup symbols or codes inserted in a file intended for display on a World Wide Web browser page. The markup tells the Web browser how to display a Web page's words and images for the user. Each individual markup code is referred to as an element (but many people also refer to it as a tag). Some elements come in pairs that indicate when some display effect is to begin and when it is to end.
DHTML
Dynamic HTML is a collective term for a combination of new Hypertext Markup Language (HTML) tags and options that will let you create Web pages that are more animated and more responsive to user interaction than previous versions of HTML. Much of dynamic HTML is specified in HTML 4.0. Simple examples of dynamic HTML pages would include (1) having the color of a text heading change when a user passes a mouse over it or (2) allowing a user to "drag and drop" an image to another place on a Web page. Dynamic HTML can make Web documents look and act like desktop applications or multimedia productions.
XML
XML (Extensible Markup Language) is a flexible way to create common information formats and share both the format and the data on the World Wide Web, Intranets and elsewhere. For example, computer makers might agree on a standard or common way to describe the information about a computer product (processor speed, memory size, and so forth) and then describe the product information format with XML. Such a standard way of describing data would enable a user to send an intelligent agent (a program) to each computer maker's Website, gather data, and then make a valid comparison. Any individual or group of individuals or companies that wants to share information in a consistent way can use XML.
CSS
A Cascading Style Sheet (CSS) is a Web page derived from multiple sources with a defined order of precedence where the definitions of any style element conflict. The Cascading Style Sheet, level 1 (CSS1) recommendation from the World Wide Web Consortium (W3C), which is implemented in the latest versions of the Netscape and Microsoft Web browsers, specifies the possible style sheets or statements that may determine how a given element is presented in a Web page.
.NET Framework
A programming infrastructure created by Microsoft for building, deploying, and running applications and services that use .NET technologies, such as desktop applications and Web services. The .NET Framework contains three major parts: the Common Language Runtime (CLR), the Framework Class Library, and ASP.NET.
ASP/Perl
Perl (Practical Extraction and Reporting Language) is a script programming language that is similar in syntax to the C language and that includes a number of popular UNIX facilities such as sed, awk, and tr. Perl is an interpreted language that can optionally be compiled just before execution into either C code or cross-platform bytecode. When compiled, a Perl program is almost as fast as a fully precompiled C language program. Perl is regarded as a good choice for developing Common Gateway Interface (CGI) programs because it has good text manipulation facilities (although it so handles binary files). Larry Wall invented it.
Java
Java is a programming language expressly designed for use in the distributed environment of the Internet. It was designed to have the "look and feel" of the C++ language, but it is simpler to use than C++ and enforces an object-oriented programming model. Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network. It can also be used to build a small application module or applet for use as part of a Web page. Applets make it possible for a Web page user to interact with the page.
SQL
SQL (Structured Query Language) is a standard interactive and programming language for getting information from a database and updating it. Although SQL is both an ANSI and an ISO standard, many database products support SQL with proprietary extensions to the standard language. Queries take the form of a command language that allows you to select, insert, update, find out the location of data and so forth. There is also a programming interface.
