Front

All digital data can ultimately be represented in binary using only combinations of the digits zero and one.

Back

True

Front

“How do you like your coffee?” is a binary question.

Back

False

Front

Mikail is sending a large video file to his teacher as part of a class project. Which of the following is most likely true if Mikail chooses to compress the video before sending it?

Back

The video will require fewer bits to be represented.

Front

Which statement best describes how computing devices represent data? Options: Computers represent data as bits or bytes, but not both. Computers represent data as bits, which contain 8 bytes. Computers represent data as bits, which are either a 0’s or 1’s. Computers represent all data as pixels.

Back

Computers represent data as bits, which are either a 0’s or 1’s.

Front

What is the highest value we can represent with 9 bits?

Back

1,023

Front

Which statement accurately describes the use of intellectual property? Options: There is no requirement to cite content produced by others if both the original content and your use of the content are digital. Data generated on a device is not owned by anyone. Creative Commons has significantly slowed down the spread and availability of digital content. Creative Commons empowers creators to distribute their content freely, which would typically be protected by copyright laws.

Back

Creative Commons empowers creators to distribute their content freely, which would typically be protected by copyright laws.

Consider the following three binary values: 0000 1010, 0001 0000, and 0000 1110. Which of the following lists the values in order from greatest to least?

Back

0001 0000, 0000 1110, 0000 1010

Front

Which statement accurately describes how numbers are represented in computers?

Back

When a computer uses a fixed number of bits, certain numbers may be too large to be represented, resulting in overflow errors.

Front

When you text a friend, your phone converts each character to its ASCII binary equivalent and each 1 and 0 is then converted to electrical impulses (on’s and off’s). The receiving phone converts the electrical impulses back to 1’s and 0’s, and then uses the ASCII protocol to convert each byte to a character. This is an example of:

Back

Binary encoding

Front

When visiting a museum, Larry takes a photo of a painting with his smart phone which stores the photo as a .jpg file. Which of the following best describes the differences between the painting itself and the photo of the painting stored on the smart phone?

Back

The photo represents the analog painting in digital form.
