Answer- The term computer graphics include almost every thing on computer that is not text or sound. It is an art of drawing pictures, lines. Or we can say that graphics is the representation and manipulation of image data by computer with the help from specialized software and hardware. Write the important applications of computer graphic?

Answer- Following are the applications of computer graphic 1. It is used to produce illustrations for reports or to generate slide for with projections. Computer graphic methods are widely used in both fine are and commercial are applications. The artist uses a combination of 3D modeling packages, texture mapping, drawing programs and CAD software.

In the field of entertainment CG methods are now commonly used in computr motion pictures. Computer-generated models of physical, grsphics and economic systems are often used as educational aids. Question-3 What are the raster and vector graphics? Raster image are stored in image files with varying formats.

VECTOR- Vector graphics is the use of geometrical primitives such as points, lines, curves, and ccs2401 or polygon, which are all based on mathematical expressions, to represent image in computer graphics. Question-4 Write the difference between vector and raster graphics? Raster or Bitmap images are resolution dependent because of this its not possible to increase or decrease their size without sacrificing on image quality. While vector based image are not dependent on resolution.

The size grapics vector image image can be increased or decreased without affecting image quality. Raster or bitmap images are always rectangular graphifs shape, Vector image, however, can have any shape. Question-5 What is scaling in computer graphics? Answer- In computer graphic, image scaling is the process of resizing a digital image. Question-6 What are the hardware devices used for computer graphics? Answer- Features of inkjet printers are- 1. They can print 2 to 4 pages per minute.

Therefor better print quality is achieved. The operating cost is very low. The only part that requires replacement is ink cartridge. Four colors cyan, yellow, magenta, black are available. Question-8 What are the advantages of electrostatic plotters? They are faster then pen plotters and very high quality printers. Recent electrostatic plotters includes a scan conversion capability. They make multiple passes over the paper to plot color picture. Question-9 What is meant by scan code? Answer- When a key is pressed on the keyboard, the keyboard controller places a code carry to the key pressed in to the part of the memory called as the keyboard buffer.

This code is called as scan code. Question Define Random and Raster scan displays? Answer- Random scan is a method in which display is made by electronic beam, which is directed only to the points or parts of the screen where picture is to be drawn. The Raster scan system is a scanning technique in which the electron sweep from top to bottom and compkter left to right.

The intensity is turned on or off to light and unlighte the pixel. What do you mean by computer graphics? The branch of science and technology concerned with methods and techniques for converting data to or from visual presentation using computers.

What are the applications of computer graphics?
