Computer
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks.
Computer Graphics
Computer graphics are pictures and films created using computers. Usually, the term refers to computer-generated image data created with help from specialized graphical hardware and software. It is a vast and recent area in computer science. The phrase was coined in 1960, by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, though sometimes erroneously referred to as computer-generated imagery (CGI).
Graphics
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 computer-aided design and manufacture, in typesetting and the graphic arts, and in educational and recreational software. Images that are generated by a computer are called computer graphics.
Image
An image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.

His own image; no longer a dark, gray bird, ugly and disagreeable to look at, but a graceful and beautiful swan. To be born in a duck's nest, in a farmyard, is of no consequence to a bird, if it is hatched from a swan's egg.

If you were to really hate and dislike a picture with all your heart, so that you could not bear to see or hear of it, how would you like it if someone insisted on getting to know and honor you through such a hated, horrible book? ... And God says that he does not like any image which we make, and ... that he hates and despises all who love images.
Andreas Karlstadt, On the Removal of Images (1522), p. 109

Can any one deny that the old Israelites conceived Jahveh not only in the image of a man, but in that of a changeable, irritable, and, occasionally, violent man?
