1.  Define Graphic & Image.  What is the difference in the two?

~ A graphic is any type of visual presentation that can be displayed on a physical surface such as a sheet of paper, wall, poster, blackboard, or computer monitor where as an image is a two- or three-dimensional representation of a person, animal, object, or scene, in the nature world. 

2.  Explain the difference between Raster & Vector images.  What are the advantages/disadvantages of each?  Embed an image(s) that illustrates each.

~ A raster image is formed by dividing the area of an image into a rectangular matrix of rows and columns comprised of pixels where as a vector image defines the area of a picture  using paths made up of points, lines, curves, and shapes. An advantage is a simple data structure. Some disadvantages are an inaccurate area and graphical calculations and a large storage requirements. Vector images have crisp edges with no aliasing. They can be resized up or down to any size without negative consequences. Vector imaging uses mathematically constructed paths to define a graphic's visual structure. Some advantages are the definitions of the image quality will always remain the same and small file sizes. Some disadvantages are lower color quality and not good photographic images.

3.  Why should you avoid upscaling whenever possible?

~ This should be avoided because when upscaling you change the quality of the pixels and you lose image detail and sharpness. The more you enlarge a raster image, the softer and fuzzier it becomes. For this specific reason, you should avoid upscaling. 

4.  What is the difference between Aliased and Anti-Aliased text?  Embed an image(s) that illustrates each.

~ Anti-aliasing smoothes out the edges of jagged type by blending the color transition points, such as the pixels along the edges of a letter. Aliasing is a stair-step effect caused by using square pixels to define objects with curves or diagonal lines. It has more extrusive jagged edges.
