What are the TWO main types of digital graphics?
Correct Answer
B. Bitmap (raster) and vector
Explanation
The correct answer is bitmap (raster) and vector. Bitmap or raster graphics are made up of pixels and are best for representing complex images or photographs. Vector graphics, on the other hand, are made up of mathematical formulas and are best for representing simple images or logos.
3.
What makes up a raster image?
Correct Answer
C. Pixels
Explanation
A raster image is made up of pixels. Pixels are the smallest units of a digital image that are arranged in a grid-like pattern. Each pixel contains information about its color and brightness, and when combined together, they form the complete image. The more pixels there are in an image, the higher its resolution and level of detail. Therefore, pixels are the fundamental building blocks of a raster image.
4.
Which term means 'converting an image into a grid of pixels?
Correct Answer
C. Rasterizing
Explanation
Rasterizing refers to the process of converting an image into a grid of pixels. This involves breaking down the image into small squares called pixels, each containing color information. By converting an image into a grid of pixels, it becomes easier to display and manipulate the image on digital devices such as computer screens. Therefore, out of the given options, rasterizing is the term that best describes the process of converting an image into a grid of pixels.
5.
A vector image is made using a mathematical formula with scalable lines and curves
Correct Answer
A. True
Explanation
A vector image is created using mathematical formulas to define lines and curves, allowing it to be scaled to any size without losing quality. This means that whether the image is displayed on a small screen or printed on a large poster, it will always appear sharp and clear. Unlike raster images, which are made up of pixels and can become pixelated when enlarged, vector images retain their smoothness and precision. Therefore, the statement that a vector image is made using a mathematical formula with scalable lines and curves is true.
6.
What is image resolution?
Correct Answer
B. The number of pixels per inch
Explanation
Image resolution refers to the number of pixels per inch (PPI) in an image. Pixels are the smallest units that make up a digital image, and the higher the number of pixels per inch, the more detail and clarity the image will have. This measurement is important when it comes to printing or displaying images, as a higher resolution will result in a sharper and more defined image. Therefore, the correct answer is "the number of pixels per inch."
7.
In relation to image resolution , what does ppi stand for?
Correct Answer
B. Pixels per inch
Explanation
The correct answer for this question is "pixels per inch". PPI stands for pixels per inch, which refers to the measurement of pixel density in an image. It indicates the number of pixels that are present in a one-inch linear distance. A higher PPI value signifies a higher resolution and sharper image quality, while a lower PPI value indicates a lower resolution and less detail in the image.
8.
In relation to image resolution, what does dpi stand for?
Correct Answer
A. Dots per inch
Explanation
DPI stands for dots per inch in relation to image resolution. It refers to the number of dots or pixels that can be displayed per inch in a printed or digital image. A higher DPI indicates a higher level of detail and sharpness in the image, while a lower DPI may result in a more pixelated or blurry appearance.
9.
What image resolution is most common for computer screens?
Correct Answer
B. 72 dpi
Explanation
The most common image resolution for computer screens is 72 dpi. This is because computer screens are typically designed to display images at a standard resolution of 72 dots per inch. This resolution provides a good balance between image quality and file size, allowing for smooth and clear display of images on computer screens. Higher resolutions may not be necessary for computer screens as they can result in larger file sizes and slower loading times.
10.
What is the minimum image resolution for printing?
Correct Answer
C. 150 dpi
Explanation
The minimum image resolution for printing is 150 dpi. DPI stands for dots per inch and refers to the number of dots or pixels that can be printed within a one-inch area. A higher DPI results in a higher quality and sharper image, while a lower DPI may lead to pixelation and loss of detail. Therefore, 150 dpi is the minimum resolution required for a satisfactory print quality.
11.
Which are the major file formats for raster images?
Correct Answer(s)
