On a scale of Baby Yoda, how are you feeling today?

Multiple Select

A computer program uses 4 bits to represent nonnegative integers. Which of the following operations would create an overflow error?

• 4 + 8

• 5 + 11

• 9 + 6

• 7 + 10

• 12 + 3

Multiple Choice

When using bits to represent fractions of a number, can you create all possible fractions?

• Yes

• No

Multiple Choice

Your computer uses 4 bits to represent decimal numbers (0, 1, 2, 3 and so on) in binary. What is the SMALLEST number for which an overflow error occur?

• 14

• 15

• 16

• 17

Multiple Choice

Which of the following is true of how computers represent numbers?

• With a fixed number of bits some numbers are too large to represent in a computer which will lead to overflow errors.

• Using a fixed but large number of bits can eliminate the possibility of round off error when representing numbers in binary

• Using a fixed but large number of bits, for example 128, eliminates the possibility of overflow errors.

• With a large but fixed number of bits it is possible to eliminate either round-off errors or overflow errors, but not both.

Multiple Choice

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 can no longer be represented using bits.

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

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

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

Multiple Choice

Multiple Choice

Which of the following is true of intellectual property?

• 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.

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

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

Multiple Choice

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?

• Modifying a piece of open source software.

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

• Failing to publish her work under a Creative Commons license

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

Multiple Choice

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

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

• Lisa owns the photo because she was the original creator and did not license the work.

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

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