Questions and Answers
- 1.
This type of image is created or "drawn" on the screen according to mathematical algorithms.
- A.
Bitmapped
- B.
Vector
- C.
Raster
Correct Answer
B. VectorExplanation
Vector images are created or "drawn" on the screen using mathematical algorithms. These algorithms define the shape, size, and position of each element in the image using mathematical equations. This allows vector images to be scaled up or down without losing any quality, as the image is essentially a set of instructions for the computer to follow. In contrast, bitmapped and raster images are made up of a grid of pixels and do not use mathematical algorithms to define the shapes in the image.Rate this question:

Which type of graphic can be resized without any loss of quality?
- A.
Bitmapped
- B.
Vector
Correct Answer
B. VectorExplanation
Vector graphics can be resized without any loss of quality because they are created using mathematical equations and geometric shapes. Unlike bitmapped graphics, which are made up of individual pixels, vector graphics can be scaled up or down without losing any detail or becoming pixelated. This is because the mathematical equations used to create the image are recalculated to fit the new size, resulting in a smooth and crisp image at any scale.Rate this question:

Which type of graphic is resolution-dependent?
- A.
Raster
- B.
Vector
Correct Answer
A. RasterExplanation
Raster graphics are resolution-dependent, meaning that they are made up of a grid of pixels and their quality is determined by the number of pixels per inch (PPI) or dots per inch (DPI). When a raster graphic is enlarged or zoomed in, the individual pixels become more visible, resulting in a loss of image quality. On the other hand, vector graphics are resolution-independent, as they are created using mathematical equations and can be scaled up or down without losing any quality.Rate this question:

Bitmap graphics are also referred to as ____________ graphics.
Correct Answer
raster
Raster
RASTERExplanation
Bitmap graphics are also referred to as raster graphics. The term "raster" refers to a grid of pixels that make up an image. In bitmap graphics, each pixel is individually defined and colored, allowing for precise control over every element in the image. The term "raster" is commonly used to describe this type of graphics, regardless of whether it is written in lowercase or uppercase.Rate this question:

Bitmapped images are composed of a collection of colored dots, called ____________________.
Correct Answer
pixels
Pixels
PIXELSExplanation
Bitmapped images are composed of a collection of colored dots called pixels. Pixels are the smallest unit of information in a digital image, and they represent the different colors and shades that make up the image. Each pixel contains specific color information, such as RGB values, which combine to create the overall visual representation of the image. The correct answer is pixels, as it accurately describes the individual dots that form a bitmapped image.Rate this question:

Photographs are best stored as to which type of image?
- A.
Raster
- B.
Vector
Correct Answer
A. RasterExplanation
Photographs are best stored as raster images because they are made up of a grid of pixels. Raster images are resolution-dependent, meaning that the quality of the image is determined by the number of pixels per inch (PPI) or dots per inch (DPI). This allows for more accurate representation of the photograph's details and colors. In contrast, vector images are made up of mathematical formulas and are best suited for graphics that require scalability and precise shapes, such as logos or illustrations. However, when it comes to storing photographs, raster images provide the most realistic and high-quality representation.Rate this question:

Which of the following applications edit bitmapped images?
- A.
Photoshop
- B.
Fireworks
- C.
Freehand
- D.
Illustrator
- E.
GIMP
Correct Answer(s)
A. pHotoshop
B. Fireworks
E. GIMPExplanation
Photoshop, Fireworks, and GIMP are all applications that edit bitmapped images. Photoshop is a widely used and powerful image editing software that allows users to manipulate and enhance bitmapped images. Fireworks is another popular application that specializes in web graphics and allows users to edit and optimize bitmapped images for the web. GIMP is a free and open-source image editing software that also supports editing bitmapped images and offers a wide range of tools and features for image manipulation. These applications are commonly used by graphic designers, photographers, and digital artists to edit and enhance bitmapped images.Rate this question:

An image that is 4 in X 4 in at 72 dpi contains how many pixels?
Correct Answer(s)
82944
82,944Explanation
4in x 72 dpi = 288 pixels across and 288 pixels high.
288 x 288 = 82,944 pixels total.Rate this question:

The process of converting a vector image into a bitmap is called...
- A.
Cross-mapping
- B.
Rasterization
- C.
Upconversion
- D.
Defragmenting
Correct Answer
B. RasterizationExplanation
Rasterization is the correct answer because it refers to the process of converting a vector image, which is composed of mathematical equations and lines, into a bitmap image, which is composed of pixels. Rasterization involves determining the color value of each pixel in the bitmap based on the mathematical equations and lines of the original vector image. This process is commonly used in computer graphics and allows for the display of vector images on raster-based devices such as computer screens and printers.Rate this question:

If a bitmapped image is enlarged and becomes fuzzy and unclear, it is said to have been...
- A.
Diffused
- B.
Rasterized
- C.
Pixilated
- D.
Embossed
- E.
Concatenated
Correct Answer
C. PixilatedExplanation
When a bitmapped image is enlarged and becomes fuzzy and unclear, it is said to have been pixilated. This means that the individual pixels that make up the image have become more visible and distorted, resulting in a loss of clarity and sharpness. This often occurs when an image is enlarged beyond its original resolution, causing the pixels to stretch and become more noticeable, leading to a blurry appearance.Rate this question:

- A.
.bmp
- B.
.gif
- C.
.tiff

A simple black-line drawing of a cube to use as a graphic in a logo for a business would best be created as to which type of graphic?
- A.
Bitmapped
- B.
Vector
Correct Answer
B. VectorExplanation
Almost all logos of this type would benefit from being a vector image. In this way, they can be resized for all kinds of purposes including letterhead, signs, business cards, etc.Rate this question:

Which graphic formats will allow you to make use of transparency?
- A.
PNG
- B.
JPG
- C.
GIF
- D.
BMP
- E.
TIFF
Correct Answer(s)
A. PNG
C. GIFExplanation
PNG and GIF are the graphic formats that allow you to make use of transparency. PNG (Portable Network Graphics) supports both transparent backgrounds and partial transparency, making it ideal for web design and digital images. GIF (Graphics Interchange Format) also supports transparency by allowing one color to be designated as transparent, which is useful for creating simple animations and logos with transparent backgrounds. On the other hand, JPG (Joint Photographic Experts Group), BMP (Bitmap), and TIFF (Tagged Image File Format) do not support transparency.Rate this question:
