Lucy is completing a project as part of a science class using materials she found online. Which of the following is MOST LIKELY to lead to legal consequences?

• Using images posted online by another student without permission or citation.

• Failing to publish her work under a Creative Commons license.

• Using open access research for which she does not acquire a license.

• Modifying a piece of open source software.

Jorge is sending a large image file to a friend as part of a shared classroom project. Which of the following is most likely true if Jorge opts to compress the image before sending it?

• The image will require more pixels to display it on the screen

• The image will require fewer bits in order to be represented.

• The image can no longer be represented using bits.

• The image will have been converted into an analog form.

Which of the following is NOT true of how computers represent complex information?

• Abstraction helps represent complex information by surfacing complexity that might otherwise be hidden

• Computing devices use patterns of bits to represent complex information

  
  

• Common abstractions that are represented by computing devices include numbers, characters, and color.

• Computing devices use patterns of bits to represent complex information

Depending on context the same sequence of bits may represent different types of information

• 10100

• 10010

• 00101

• 11000

Which of the following is true of intellectual property?

• Creative Commons has severely hindered broad and open access to digital information

• Creative Commons enables content creators to freely distribute their otherwise copyrighted work

• Information created on a computer is not owned by anyone since only analog information is protected under copyright law.

• You do not need to cite work created by someone else if both the original work and your use of it are in digital form.

Which of the following best describes how computing devices represent information?

• A computer represents information as bits which contain 8 bytes.

• A computer represents data as bits which is either a 0 or a 1

• A computer represents data as a byte which is either a 0 or a 1

• A computer will either represent information as bits or bytes but not both

Ryan is designing an app that needs to quickly send low quality photos between users. Most smartphones take much higher quality photos than Ryan needs for his app. Which answer best describes the type of compression Ryan should choose and why?

• Lossless compression since it typically results in smaller data sizes.

• Lossless compression since it ensures perfect reconstruction of the photo.

• Lossy compression since it typically results in smaller data sizes.

• Lossy compression since it ensures perfect reconstruction of the photo.

Arman takes a picture with his smartphone which he subsequently posts online. Beatrice finds the picture online and posts a copy of it on her website with an attached Creative Commons license. Which of the following best describes who owns the photo?

• Arman owns the photo because he was the original creator and did not license the work.

• Arman owns the photo because it was granted a Creative Commons license by another person online.

• Beatrice owns the photo because only holders of a Creative Commons license can own works online.

• Both own the photo because creating a copy makes it her intellectual property.
