1.
Vector images lose quality when you enlarge them.
Correct Answer
B. False
Explanation
Vector images do not lose quality when you enlarge them. Unlike raster images, which are made up of pixels and can become pixelated when enlarged, vector images are made up of mathematical equations and can be scaled up or down without losing any quality. This is because vector images are based on paths and curves rather than fixed pixels. Therefore, enlarging a vector image will not result in any loss of quality.
2.
Vector images are best for photos.
Correct Answer
B. False
Explanation
Vector images are not best for photos. Vector images are created using mathematical equations and are best suited for graphics such as logos, icons, and illustrations. They are resolution-independent and can be scaled without losing quality. However, when it comes to photos, which are raster images made up of pixels, vector images are not suitable as they cannot capture the intricate details and color variations present in a photograph. Raster images, on the other hand, are better suited for representing photos as they can capture the fine details and color gradients accurately.
3.
Which file generally has the smaller filesize?
Correct Answer
B. Vector
Explanation
Vectors are generally smaller in filesize compared to bitmaps because vectors use mathematical equations to define shapes and lines, while bitmaps are made up of individual pixels. Vectors are resolution-independent, meaning they can be scaled up or down without losing quality, whereas bitmaps are resolution-dependent and can become pixelated when scaled up. Additionally, vectors only store the mathematical equations and instructions needed to recreate the image, resulting in smaller file sizes compared to bitmaps that store color information for each individual pixel.
4.
If we wish to make an icon, which software is usually the better option?
Correct Answer
A. Illustrator
Explanation
Illustrator is usually the better option for making icons because it is a vector-based software that allows for precise and scalable designs. Icons often need to be resized for different purposes, such as on websites or mobile apps, and Illustrator's vector graphics ensure that the quality and clarity of the icon is maintained regardless of the size. Additionally, Illustrator offers a wide range of tools and features specifically designed for creating and editing vector artwork, making it the preferred choice for creating clean and professional-looking icons.
5.
Bitmap files lose quality when you enlarge them.
Correct Answer
A. True
Explanation
When a bitmap file is enlarged, the pixels in the image are stretched, resulting in a loss of quality. Bitmap images are made up of a fixed number of pixels, and when the image is enlarged, the pixels become more spread out, causing a decrease in resolution and clarity. This is because bitmap images store information about each individual pixel, so when the image is enlarged, the software has to interpolate and guess the colors of the new pixels, leading to a loss of detail and sharpness. Therefore, it is true that bitmap files lose quality when enlarged.
6.
Which software is usually better for creating scientific diagrams?
Correct Answer
B. Illustrator
Explanation
Illustrator is usually better for creating scientific diagrams because it is a vector-based software that allows for precise and scalable illustrations. It offers a wide range of tools and features specifically designed for creating complex diagrams, graphs, and charts. Additionally, Illustrator provides better control over line weights, shapes, and colors, making it suitable for creating detailed scientific visualizations. Photoshop, on the other hand, is primarily used for editing and manipulating raster images, which may not provide the same level of accuracy and flexibility required for scientific diagrams.
7.
The top zoomed-in picture is a:
Correct Answer
A. Vector grapHic
Explanation
The top zoomed-in picture is most likely a vector graphic because vector graphics are composed of mathematical equations and geometric shapes, allowing them to be infinitely scalable without losing quality. This means that when zoomed in, a vector graphic will still maintain its sharpness and clarity. On the other hand, bitmap graphics are made up of pixels and can become pixelated or blurry when zoomed in too much.
8.
A vector image is made up of a matrix of dots (pixels).
Correct Answer
B. False
Explanation
A bitmap image is made of many pixels, not a vector image.
9.
If natural tones are required, the better software is:
Correct Answer
A. pHotoshop
Explanation
Photoshop is the better software if natural tones are required because it offers more advanced tools and features specifically designed for photo editing. It provides a wide range of adjustment options such as color correction, tone mapping, and blending modes that allow for precise control over the tones in an image. Illustrator, on the other hand, is primarily used for vector graphics and is not as specialized for working with natural tones in photographs.
