DotNetNuke is an open source [5] web application framework [6] written in VB.NET for the ASP.NET framework. The application's content management system is extensible and customizable through the use of skins and modules, and it can be used to create, deploy, and manage intranet, extranet, and web sites.

Computer science (or computing science) is the study of the theoretical foundations of information and computation and their implementation and application in computer systems.^[1][2][3] Computer science has many sub-fields; some emphasize the computation of specific results (such as computer graphics), while others relate to properties of computational problems (such as computational complexity theory). Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describing computations, while computer programming applies specific programming languages to solve specific computational problems. A further subfield, human-computer interaction, focuses on the challenges in making computers and computations useful, usable and universally accessible to people.
