Module 7 Flashcards
ANo _____ file uses lossy compression, which discards some of the original file data during compression.
A.
GIF
B.
SVG
C.
WAV
D.
JPG or JPEG
D. JPG or JPEG
Explanation:
JPEG files use lossy compression, meaning some original data is discarded to reduce the file size. This makes JPEG ideal for images where reduced size is more important than perfect quality. Other formats like GIF and WAV use different compression or are lossless formats
Mobile games were the first to popularize _____, which uses an image of an actual place or thing and adds digital information to it.
A.
computer-aided design (CAD)
B.
mixed reality (MR)
C.
augmented reality (AR)
D.
virtual reality (VR)
C. augmented reality (AR)
Explanation:
Augmented Reality (AR) overlays digital content on the real world. Mobile games like Pokémon GO popularized AR by combining real-world views with virtual elements
Most _____ shows media on a timeline with separate tracks for video and sound.
A.
image editing software
B.
stock photo galleries
C.
video consoles
D.
video editing software
D. video editing software
Explanation:
Video editing software allows users to arrange and edit video and audio tracks along a timeline, providing better control over synchronization and effects
_____ refers to the clarity or sharpness of an image.
A.
Compression
B.
In-betweening
C.
Bit rate
D.
Resolution
D. Resolution
Explanation:
Resolution refers to the number of pixels in an image, determining its sharpness and clarity. Higher resolution images contain more detail
What type of software do engineers and scientists use to create wireframe drawings of objects, which they can rotate to view from many angles?
A.
3-D CAD software
B.
photo-editing software
C.
spatial recognition software
D.
animation software
A. 3-D CAD software
Explanation:
3-D CAD (Computer-Aided Design) software allows users to create complex models, including wireframes, that can be viewed and rotated from various perspectives
Of all types of digital media, digital video files are the smallest and download faster than the other types. True or false?
Answer: False
Explanation:
Digital video files are usually larger than other types of media, such as images or audio, due to the amount of data required for video and audio tracks
A scanner converts a printed document into a bitmap file by dividing the image into a grid of tiny cells and assigning colors to each cell. True or false?
True
Explanation:
Scanners use bitmap technology by converting images into grids of pixels (tiny cells) and assigning a color to each pixel. This process digitizes physical documents
A _____ combines speakers and a microphone into one device.
A.
camcorder
B.
headset
C.
hologram
D.
sound card
B. headset
Explanation:
A headset integrates both speakers and a microphone, making it suitable for communication purposes, such as online meetings and gaming
A ______ is an image you can see, store, and manipulate on a digital device.
A.
sound wave
B.
digital graphic
C.
geotag
D.
digital assistant
B. digital graphic
Explanation:
A digital graphic refers to any image created, manipulated, or stored on a computer or digital device, such as photos or illustrations
A process called _____ converts analog sound waves into digital sound.
A.
sampling
B.
in-betweening
C.
augmenting
D.
simulating
A. sampling
Explanation:
Sampling converts continuous analog signals into discrete digital data by measuring the sound wave at regular intervals. This is how sound is digitized for playback on computers
When you stream digital media, you must transfer the entire video or audio file to your computer. True or false?
False
Explanation:
In streaming, data is transmitted in small packets in real time, so the entire file does not need to be downloaded before playback begins
A _____ is a sophisticated computer animation useful for training and teaching in many fields.
A.
motion-sensing game
B.
keyframe
C.
simulation
D.
transition
C. simulation
Explanation:
Simulations use computer-generated models to replicate real-world processes for training and educational purposes, such as flight simulators
With a search engine, you can use a ____ to search for pictures that you can use, share, or modify for personal or commercial use.
A.
pixel
B.
graphics tablet
C.
license filter
D.
codec
C. license filter
Explanation:
A license filter helps users find images with specific usage rights, ensuring they only use media that is legally permitted for sharing or modification
Of the two types of digital animation, 2-D animation is considered superior to 3-D animation. True or false?
False
Explanation:
While 2-D animation has its advantages, 3-D animation is often considered more advanced because it offers more realism and versatility in fields like movies and games
