Question 1

Vasily is designing a simulation tool that will let students practice assembling computers. Which format should he use for the animations?
A) HTTPS
B) HTML 5
C) JPEG
D) SWF

Accepted Answer

HTML 5 is the best format for animations as it is widely supported and can be easily integrated into websites and applications. HTTPS is a secure protocol for transmitting data over the internet and is not relevant for animation formats. JPEG is a format for still images, not animations. SWF, or Shockwave Flash, was once popular for web animations but is now largely unsupported and has security vulnerabilities.

Question 2

Which of the following is NOT a type of digital media?
A) An online video
B) A painting
C) A website's logo
D) A ringtone

Accepted Answer

Digital media refers to any media that can be created, viewed, distributed, modified, and preserved on digital devices and networks. A painting is a physical medium that cannot be viewed or distributed digitally, so it is not a type of digital media. On the other hand, online videos, website logos, and ringtones can all be created, distributed, and viewed digitally.

Question 3

Which of the following values can be represented by a single bit?
A) 1
B) cat
C) A
D) 1000

Accepted Answer

A single bit can represent a binary value of either 0 or 1, therefore it can represent the value of 1.

Question 4

What technology allows Alexa and Siri personal assistants to respond to questions and follow verbal instructions to perform tasks?
A) Machine learning
B) Real-time animation
C) Live video streaming
D) Artificial intelligence

Accepted Answer

Alexa and Siri personal assistants use artificial intelligence technology to understand and interpret natural language voice commands and provide responses and perform tasks.

Question 5

How can you ensure you can legally use images found on Google?
A) Read the license and follow its restrictions
B) Use the image only for school
C) Give credit to the source
D) Send PayPal money to the image owner

Accepted Answer

Reading the license and following its restrictions is the best way to ensure that you can legally use images found on Google. This will tell you if you need to give credit to the source, if you can use it for commercial purposes, and if there are any other restrictions on its use. Using the image only for school or giving credit to the source may not be enough if the license does not allow for such use. Sending PayPal money to the image owner is not a reliable way to ensure legal use of an image and may not be necessary depending on the license.

Question 6

What kind of digital media is an online broadcast of the Super Bowl as it happens?
A) Live audio feed
B) On-demand content
C) Live video streaming
D) Downloaded video

Accepted Answer

The online broadcast of the Super Bowl is a live video streaming, as it is happening in real-time and being broadcasted in video form over the internet. Live audio feed is only the sound, and on-demand and downloaded video are not happening in real-time.

Question 7

Toby needs a high-quality graphic for a background to his new website. Where can he get one legally?
A) Facebook
B) Microsoft
C) Shutterstock
D) Instagram

Accepted Answer

Shutterstock specifically offers licensed, high-quality graphics for use in design projects. Facebook and Instagram may have images that are copyrighted and require permission to use, and Microsoft could have limitations on the type of graphics that can be used for website backgrounds.

Question 8

How can you identify the format of a file?
A) Check what program opens the file
B) Check what program created the file
C) Check the file size
D) Check the file name extension

Accepted Answer

The file's format can typically be identified by the file name extension, which is the characters that come after the period in the file name. Different file formats often have different extensions (e.g. .docx for Microsoft Word documents, .jpg for image files, .mp3 for audio files). Checking what program opens or created the file, as well as the file size, can provide some clues but may not always be accurate in determining the file format.

Question 9

If you're about to download a photo that is labeled "high quality", what else can you assume about the photo?
A) It has a large file size.
B) It's a color photo.
C) It's an analog photo.
D) It's an expensive download.

Accepted Answer

High quality photos usually have a higher resolution and therefore a larger file size.

Question 10

Which file type will yield the best audio quality, even when compressed?
A) MP3
B) AAC
C) WMA
D) M4P

Accepted Answer

The answer of Which file type will yield the best...

Question 11

What kind of technology can traffic engineers use to determine the best timing for red light cycles at an intersection of two major highways?
A) Machine learning
B) Real-time animation
C) 3-D CAD software
D) Augmented reality

Accepted Answer

Traffic engineers can use machine learning algorithms to analyze traffic patterns and make predictions about traffic flow at different times of day. This can help them determine the best timing for red lights at an intersection to help reduce traffic congestion and improve overall traffic flow. Real-time animation, 3-D CAD software, and augmented reality are not typically used for this type of analysis.

Question 12

Why are vector images typically used for logos instead of bitmap images?
A) Some types of bitmap graphics use lossy compression.
B) A vector image is a grid of pixels that forms an image.
C) Bitmap graphics are created by mathematical formulas.
D) Vector images are not resolution dependent.

Accepted Answer

Vector images are not resolution dependent, which means they can be resized without losing image quality. Logos need to be easily scalable to be used in various sizes, and vector images are suitable for this purpose. Bitmap images, on the other hand, use pixels to create an image, and when resized, the pixels can become distorted and the image can lose quality.

Question 13

Elliott is about to buy a new computer. He knows he needs to use the Windows Ink feature to draw notes on webpages he finds when he researches projects for school. What hardware should Elliott ensure he gets?
A) Digital camera
B) Touchscreen
C) Graphics tablet
D) Scanner

Accepted Answer

Elliott needs a device with a touchscreen feature in order to use the Windows Ink feature to draw notes on webpages. Therefore, he should ensure that the computer he purchases has a touchscreen.

Question 14

Which of the following gives the most realistic experience?
A) Animation
B) Digital video
C) Virtual reality
D) Digital graphic

Accepted Answer

Virtual reality provides an immersive and interactive experience that closely simulates real-world scenarios, making it the most realistic option among the given choices. Animation and digital graphics are stylized representations, while digital video can be realistic but lacks the interactivity and immersion of virtual reality.

Question 15

Misty is playing with an app on her phone that shows star constellations on her screen as she pans her phone across the sky at night. Which of the following is the most accurate term for this kind of technology?
A) VR
B) Hologram
C) Virtual world
D) AR

Accepted Answer

The technology described in the scenario is Augmented Reality (AR), which allows digital content to be overlaid onto the real world through a device such as a smartphone. VR (Virtual Reality) is a technology that immerses the user in a completely virtual world, while a hologram is a three-dimensional image projected into space. While the app may show Misty the stars, it is not creating an entirely virtual world, making option C (Virtual World) incorrect.

Question 16

Ginny is about to rent a movie online and is trying to decide which resolution will give her the best viewing experience. She plans to watch the video on her laptop, which offers a display resolution of up to 1920 x 1080. Which video resolution should Ginny select?
A) HD
B) SD
C) 4K
D) 8K

Accepted Answer

Since Ginny's laptop can display up to 1920 x 1080, selecting HD resolution (1280 x 720 or 1920 x 1080) will give her the best viewing experience. Selecting a higher resolution such as 4K or 8K will not make any difference as her laptop display cannot support it. Selecting SD resolution (720 x 480 or 640 x 480) will result in a lower quality viewing experience.

Question 17

Cymone is starting a new business and wants to create a consistent appearance across her business cards, letterhead, and website. What kind of graphic does she need?
A) 3-D animation
B) Logo
C) Icon
D) Button

Accepted Answer

Cymone needs a logo to create a consistent appearance across her business cards, letterhead, and website. A logo will help establish her brand and make it easily recognizable to potential customers. 3-D animation, icons, and buttons may also be useful design elements for her website, but a logo is the best choice for creating consistency across all materials.

Question 18

Denver is drawing a simple cartoon on the bottom corners of his notepad. Each page's corner shows the character in a slightly different pose, and when Denver flips through the pages, the character appears to move. The movement seems sporadic, though, and choppy. How many pages per second of animation would Denver need to draw to create a more natural appearance of movement?
A) 512
B) 8
C) 24
D) 76

Accepted Answer

The standard frame rate for animation is 24 frames per second, which provides a smooth and natural movement. Therefore, Denver would need to draw 24 different poses per second to create a more natural appearance of movement. Choices A, B, and D are not reasonable frame rates for animation.

Question 19

Which type of bitmap graphic loses some of its data during compression?
A) GIF
B) TIF
C) JPEG
D) PNG

Accepted Answer

JPEG uses lossy compression, which means that some data is lost during the compression process in order to reduce file size. GIF, TIF, and PNG all use lossless compression, which maintains all of the data in the original image.

Question 20

Which of the following is NOT an example of digital media?
A) A podcast played on a smartphone
B) A video chat played on a laptop
C) An animated game played on a game console
D) A song played on an electric guitar

Accepted Answer

Digital media refers to media that is stored in digital form and can be accessed through electronic devices. Playing a song on an electric guitar is not an example of digital media because it does not involve the use of electronic devices or digital storage.
