Vector graphics have three distinct advantages over bitmapped graphics. Vector graphics are more flexible than bitmapped graphics because they look the same even when you shrink or enlarge (scale) them to different sizes. In contrast, bitmapped graphics become jagged when you scale them. Vector images also look better on devices (monitors and printers) with higher resolution, whereas bitmapped images always appear the same regardless of a device's resolution. And finally, vector images often require less memory than bitmapped images.
The other method for representing graphical images is through bit maps, in which the image is composed of a pattern of dots. These images are often called raster graphics or bitmapped graphics. Examples of raster image file types are BMP, TIFF, GIF, and JPEG files. A raster file is usually difficult to modify without loss of information
Programs that enable you to create and manipulate vector graphics are called draw programs, whereas programs that create or manipulate bitmapped images are called paint programs. Corel Draw and Adobe Illustrator are two of the leading draw programs. Corel Paint and Adobe Photoshop are two of the leading paint programs on the market.
