This quiz is for my second period computer applications II class.

• 1.

### Clipart is

• A.

Premade grapHics available online or in software

• B.

Computer created artwork or paintings - vectors or rasters

• C.

An image created from many images put into one

• D.

Raster images with millions of colors

A. Premade grapHics available online or in software
Explanation
Clipart refers to premade graphics that are readily available online or in software. These graphics are often used to enhance documents, presentations, or websites. They can be easily inserted into a project without the need for extensive design skills or creating artwork from scratch. Clipart may include various images, icons, symbols, or illustrations that can be resized, edited, and customized to fit the user's needs. It provides a convenient and time-saving solution for adding visual elements to different media.

### Aspect Ratio is

• A.

The ratio of an object's height to its width

• B.

The ratio of an object's pixels to color depth

• C.

The ratio of an object's width to its height

• D.

4:3

C. The ratio of an object's width to its height
Explanation
Aspect ratio is the ratio of an object's width to its height. This means that it represents the proportional relationship between the width and height of an object. It is commonly used in the context of screens, images, and videos to describe the shape or dimensions of the object. For example, a 16:9 aspect ratio means that the width is 16 units and the height is 9 units.

Rate this question:

• 3.

### The aspect ratio of 1024 x 768 is (hint, if you don't know, divide)

4:3
Explanation
The aspect ratio of 1024 x 768 is 4:3 because when we divide 1024 by 4, we get 256, and when we divide 768 by 3, we get 256 as well. This means that the width and height of the image have a ratio of 4:3, indicating that the width is 4 units for every 3 units of height.

### Photographs are

• A.

Images scanned into a computer for editing

• B.

Premade grapHics available online and in software

• C.

Computer created artwork or paintings - vector or raster

• D.

Raster images with millions of colors

D. Raster images with millions of colors
Explanation
Raster images are made up of a grid of pixels, where each pixel contains information about its color. These images are created using various colors and shades to form a complete picture. The term "raster" refers to the way in which these images are stored and displayed on a computer screen. Additionally, raster images can contain millions of colors, allowing for a high level of detail and realism in photographs. Therefore, the given answer accurately describes photographs as raster images with millions of colors.

• 5.

### Which resolution will have bigger icons - 1024x 768 or 640 x 480? (remember the illustration I gave when I right clicked the desktop)

640 x 480
Explanation
The resolution 640 x 480 will have bigger icons compared to 1024 x 768. This is because the resolution refers to the number of pixels displayed on the screen, and a lower resolution means fewer pixels. With fewer pixels, each individual pixel will be larger, resulting in larger icons on the screen.

Rate this question:

• 6.

### PPI is

• A.

Parts per inch

• B.

Pixels per inch

• C.

People per image

• D.

Pixels per image

B. Pixels per inch
Explanation
PPI stands for pixels per inch. It is a measurement used to describe the resolution of a digital image or display. The higher the PPI, the more pixels are packed into each inch, resulting in a sharper and more detailed image. This measurement is commonly used in the context of screens, monitors, and printing to determine the quality and clarity of visual content.

Rate this question:

• 7.

### True or False - Resolution is decreased when DPI, PPI, SPI, LPI is decreased.

True
Explanation
When DPI (dots per inch), PPI (pixels per inch), SPI (samples per inch), or LPI (lines per inch) is decreased, it means that there are fewer dots, pixels, samples, or lines per inch respectively. This results in a decrease in the overall resolution of the image or display. With fewer units of measurement per inch, the level of detail and sharpness is reduced, leading to a decrease in resolution. Therefore, the statement that resolution is decreased when DPI, PPI, SPI, or LPI is decreased is true.

Rate this question:

• 8.

### Anti aliasing

• A.

Is rough blocks that sharpen edges of an image.

• B.

Is smooth circles added to a scene.

• C.

Is smooth transitions and lines between neighboring shapes and colors.

• D.

Is feathered edges added to an image.

C. Is smooth transitions and lines between neighboring shapes and colors.
Explanation
Anti-aliasing is a technique used in computer graphics to smooth out the jagged edges of an image or text by blending the colors of the pixels along the edges. It helps to create smooth transitions and lines between neighboring shapes and colors, resulting in a more visually pleasing and realistic image. This technique is commonly used in digital imaging, video games, and computer-generated animations to improve the overall quality and visual appeal of the graphics.

Rate this question:

• 9.

### SPI is

samples per inch
• 10.

### Artwork is

• A.

Computer created drawings or paintings.

• B.

Raster images with millions of colors.

• C.

Images with many colors.

• D.

Premade grapHics available in software or online.

A. Computer created drawings or paintings.
Explanation
The correct answer is "computer created drawings or paintings." This means that artwork refers to drawings or paintings that are created using a computer. It excludes other options such as raster images with millions of colors, images with many colors, or premade graphics available in software or online.

• 11.

### When you look at a piece of paper the you can see the tiny ___ of color per inch.

dots
Explanation
When you look at a piece of paper, you can see the tiny dots of color per inch. These dots are the individual points of ink or pigment that make up the image or text on the paper. The more dots per inch, the higher the resolution and clarity of the printed material.

Rate this question:

• 12.

### ____ per inch are how many times a bar of ink is printed horizontally per inch.

lines
Explanation
The term "lines" refers to the number of times a bar of ink is printed horizontally per inch. This means that for every inch of space, the ink bar is printed a certain number of times horizontally. The answer "lines" accurately describes this concept without any further explanation needed.

Rate this question:

• 13.

### An image is ___ when its aspect ratio changes by one value on either side of the ratio (i.e. 4:3 changing to 5:3)

• A.

Enhanced

• B.

Distorted

• C.

Recolored

• D.

Blurred

B. Distorted
Explanation
When an image is distorted, its aspect ratio changes by one value on either side of the ratio. This means that the image becomes stretched or compressed in one direction, causing a loss of proportion and a change in the overall appearance of the image.
