1. Vector-Drawn Graphics

1.1. - Computer-aided design (CAD) programs needed by architects and engineers

1.2. - A vector is a line that is described by the location of its two endpoints.

1.3. - 3-D animation programs – changes of position, rotation, and shading of light

2. Vector-drawn images versus bitmaps

2.1. - Vector images use less memory space and have a smaller file size as compared to bitmaps.

2.2. - For the Web, pages that use vector graphics in plug-ins download faster and, when used for animation, draw faster than bitmaps.

2.3. - Vector objects are easily scalable without loss of resolution or image quality.

3. Bitmap (raster)

3.1. - simple matrix of tiny dots that form an image and displayed on screen/printed.

3.2. - describe the characteristics of all pixels making the image
