Word Definition
Computational Science
Computational science, also known as scientific computing, is the field of study concerned with constructing mathematical models and numerical solution techniques and using computers to analyze and solve scientific and engineering problems. In practical use, it is typically the application of computer simulation and other forms of computation to problems in various scientific disciplines such as Physics. Computational science and computer science are very different fields.
Computer Animation
Computer animation, also known as Computer generated imagery (CGI) is the art of creating moving images via the use of computers. It is a subfield of computer graphics and animation. Increasingly it is created by means of 3D computer graphics, though 2D computer graphics are still widely used. Sometimes the target of the animation is the computer itself, sometimes the target is another medium, such as film.
Computer Game
A computer game is a computer-controlled game with or without video technologies involved. In common usage, a "computer game" or a "PC game" refers to a game that is played on a personal computer. There always must also be some sort of input device, usually in the form of button/joystick combinations (on arcade games), a keyboard & mouse/trackball combination (computer games), or a controller (console games), or a combination of any of the above. Also, more esoteric devices have been used for input (see also Game controller). Usually there are rules and goals, but in more open-ended games the player may be free to do whatever they like within the confines of the virtual universe.
Computer Graphics
Computer graphics (CG) is the field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information sampled from the real world. Computer graphics field can be divided into several areas: real-time 3D rendering (often used in video games), computer animation, video capture and video creation rendering, special effects editing (often used for movies and television), image editing, and modeling (often used for engineering and medical purposes). Development in computer graphics was first fueled by academic interests and government sponsorship. However, as real-world applications of computer graphics in broadcast television and movies proved a viable alternative to more traditional special effects and animation techniques, commercial parties have increasingly funded advances in the field.
Computer Science
Computer science, or computing science, is an academic field that studys the theoretical foundations of information and computation and their implementation and application in computer systems. Computer science has many sub-fields; some emphasize the computation of specific results (such as computer graphics), while others (such as computational complexity theory) relate to properties of computational problems. Still others focus on the challenges in implementing computations. For example, programming language theory studies approache to describing computations, while computer programming applies specific programming languages to solve specific computational problems.
ConceptBase
ConceptBase is a deductive and object-oriented database management system based on Datalog rather than SQL. It stores all factual information in a single flat data structure called P-facts. On top of that deductive rules, integrity constraints, and queries are defined to capture the semantics of the application domain. The main application domain of ConceptBase is conceptual modeling, model management, and meta modeling.
Config Files: Configuration Files
In computing, configuration files (config files) are used to configure the initial settings for some computer programs. They are used for user applications, server processes and operating system settings. The files are often written in ASCII (rarely UTF-8) and line-oriented, with lines terminated by a newline or carriage return/line feed pair, depending on the operating system. They may be considered a simple database.
CONFIG.SYS
CONFIG.SYS is the primary configuration file for the MS-DOS and OS/2 operating systems. It is a special file that contains setup or configuration instructions for the computer system. The commands in this file configure DOS for use with devices and applications in the system. The commands also set up the memory managers in the system. After processing the CONFIG.SYS file, DOS proceeds to load and execute the command shell specified in the shell= line of CONFIG.SYS, or COMMAND.COM if there is no such line. The command shell in turn is responsible for processing the AUTOEXEC.BAT file.
Configuration
In communications or computer systems, configuration is the way a system is set up, or the assortment of components that make up the system. Configuration can refer to either hardware or software, or the combination of both. Often, configuration pertains to the choice of hardware, software, firmware, and documentation. The configuration affects system function and performance.
Configuration Management
In software development, configuration management is a system for keeping track of large software projects. Configuration management system include functions such as version control and automatically documents all components used to build executable programs. It is able to recreate each build as well as to recreate earlier environments in order to maintain previous versions of a product. It may also be used to prevent unauthorized access to files or to alert the appropriate users when a file has been altered.

Word : GNU/kFreeBSD
Explanation : GNU/kFreeBSD is an operating system that uses the kernel of FreeBSD in conjunction with GNU userland software. Currently, the following distributions of GNU/kFreeBSD are available: Debian GNU/kFreeBSD, Gentoo/FreeBSD. It should be noted that the k in kFreeBSD refers to the fact that only the kernel of the FreeBSD operating system is used.
