Computers reproduce photos by breaking the image up into small squares called

Pixels
Bytes
Bits

Correct Answer

A. Pixels

Explanation

Computers reproduce photos by breaking the image up into small squares called pixels. Pixels are the smallest unit of a digital image, and each pixel represents a single point of color. By combining these pixels together, the computer can recreate the entire image. Bytes and bits, on the other hand, are units of digital information storage and do not directly relate to reproducing photos.

Black and white pictures require less information because all that needs to be recorded is its position and its

Color information
Shade of gray
Location

Correct Answer

A. Shade of gray

Explanation

Black and white pictures require less information because they only need to record the shade of gray for each pixel. Unlike color pictures, which require additional information for each pixel's color values, black and white pictures can be represented with a single value for each pixel. Therefore, the amount of information needed to store and transmit black and white pictures is significantly lower.

A color pixel needs three numbers to define its color: one number each to indicate how much

Cyan, magenta, yellow
Red, yellow, blue
Red, green, and blue

Correct Answer

A. Red, green, and blue

Explanation

The correct answer is red, green, and blue. This is because a color pixel in digital imaging is typically represented using the RGB color model, where each color component is represented by a number ranging from 0 to 255. Red, green, and blue are the primary colors used in this model to create a wide range of colors by varying the intensity of each component.

Black and white images require more computer file space than color images.

True
False

Correct Answer

A. False

6.

A RASTER image is a rectangular grid of

Lines
Dots
Pixels
All of the above

Correct Answer

A. Pixels

Explanation

A raster image is a digital image that is composed of a rectangular grid of pixels. Pixels are the smallest units of a digital image, and they are used to represent the colors and details of the image. Therefore, the correct answer is "pixels" as it accurately describes the composition of a raster image.

VECTOR graphics are based on

Color depth
Mathematical equations
Photographs

Correct Answer

A. Mathematical equations

Explanation

VECTOR graphics are based on mathematical equations. Unlike raster graphics, which are based on pixels, vector graphics use mathematical formulas to represent and render images. These formulas define the shapes, curves, lines, and colors of the graphics, allowing them to be scaled and manipulated without losing quality. This makes vector graphics ideal for tasks such as logo design, illustration, and printing, where scalability and precision are important. Color depth and photographs, on the other hand, are characteristics or elements associated with raster graphics.

Adobe Illustrator is a software program that uses

Mathematical equations
Vector graphics
Bezier curves
Anchor points
None of the above
All of the above

Correct Answer

A. All of the above

Explanation

Adobe Illustrator is a comprehensive software program that incorporates various features and tools to create vector graphics. It utilizes mathematical equations to define the shapes and curves of the graphics. The use of vector graphics allows for scalability without loss of quality. Bezier curves are commonly used in Illustrator to create smooth and precise curves. Anchor points are used to define the start and end points of the curves and shape. Therefore, all of the given options - mathematical equations, vector graphics, bezier curves, and anchor points - are correct in describing the features and functionality of Adobe Illustrator.

The total number of pixels in an image is referred to as the image's

Resolution
Raster
Color depth
Both A and C
None of the above

Correct Answer

A. Resolution

Explanation

The correct answer is "resolution" because the total number of pixels in an image refers to its resolution. Resolution is a measure of the amount of detail that an image holds and is typically expressed as the number of pixels in the width and height of the image. A higher resolution means more pixels, resulting in a clearer and more detailed image. Therefore, resolution is the correct term to describe the total number of pixels in an image.

A JPEG image is a "lossy" format, which means that

The number of pixels in the image can be increased without loss of quality.
The image is compressed each time it is saved and could degrade.

Correct Answer

A. The image is compressed each time it is saved and could degrade.

Explanation

A JPEG image is a "lossy" format, meaning that it undergoes compression each time it is saved. This compression process reduces the file size by discarding some of the image data, resulting in a loss of quality. Therefore, each time a JPEG image is saved, there is a potential for degradation in its visual fidelity.

A TIFF image is most often used for work that is printed and saves

8 bits per color
16 bits per color
Both A and B

Correct Answer

A. Both A and B

Explanation

A TIFF image is commonly used for work that is printed because it can save both 8 bits per color and 16 bits per color. This flexibility allows for a wide range of color depths and ensures that the image can be accurately reproduced in print. Saving in 8 bits per color is suitable for most standard printing needs, while saving in 16 bits per color provides a higher level of detail and color accuracy for professional printing or advanced editing purposes.

Images in RAW format is "lossless"

True
False

Correct Answer

A. True

Explanation

RAW format is a type of image file that contains minimally processed data directly from the camera's sensor. It preserves all the original data captured by the sensor, including color information and dynamic range, without any compression or loss of quality. Therefore, images in RAW format are considered "lossless" because they retain all the details and information from the original image.

A GIF image uses a limited color palette and is best used for

Simple shapes and cartoon-like images
Printing photographs
Halftones

Correct Answer

A. Simple shapes and cartoon-like images

Explanation

A GIF image uses a limited color palette, typically up to 256 colors, which makes it suitable for simple shapes and cartoon-like images. This format is not ideal for printing photographs or halftones, as these require a wider range of colors and finer details. Therefore, GIF is commonly used for graphics with solid colors and sharp edges, such as logos, icons, and illustrations.

PNG images are "lossless" and therefore their file size is ______________ than JPEG images.

Smaller
Larger

Correct Answer

A. Larger

Explanation

PNG images are "lossless" because they do not lose any quality or data during compression. This means that all the original information from the image is preserved, resulting in a larger file size compared to JPEG images. JPEG images, on the other hand, use lossy compression, which sacrifices some image quality to reduce file size. Therefore, PNG images have a larger file size than JPEG images.

Scanners
Both B and C
Both A and C

Correct Answer

A. Both A and C

Explanation

BMP files are large files that are developed for use mostly with Windows programs and scanners. They are also compatible with Macintosh programs. Therefore, the correct answer is both A and C.
