What is Graphics: Definition and 116 Discussions

Graphics (from Greek γραφικός graphikos, "belonging to drawing") are visual images or designs on some surface, such as a wall, canvas, screen, paper, or stone to inform, illustrate, or entertain. In contemporary usage, it includes a pictorial representation of data, as in c manufacture, in typesetting and the graphic arts, and in educational and recreational software. Images that are generated by a computer are called computer graphics.
Examples are photographs, drawings, line art, graphs, diagrams, typography, numbers, symbols, geometric designs, maps, engineering drawings,
or other images. Graphics often combine text, illustration, and color. Graphic design may consist of the deliberate selection, creation, or arrangement of typography alone, as in a brochure, flyer, poster, web site, or book without any other element. Clarity or effective communication may be the objective, association with other cultural elements may be sought, or merely, the creation of a distinctive style.
Graphics can be functional or artistic. The latter can be a recorded version, such as a photograph, or interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred. It can also be used for architecture.

    Refurbished Graphics Card or Not

    I found a refurbished Quadro M4000 for about $250. I'm wondering if I should get this or a new card for about the same price. The M400 refurbished comes with a 4 year extended warranty so basically $300 with a 4 year warranty.
