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?

Lossy compression since it typically results in smaller data sizes.

Which of the following is true of lossy and lossless compression algorithms? Lossy compression algorithms are used when perfect reconstruction of the original data is important., Lossy compression algorithms are typically better than lossless compression algorithms at reducing the number of bits needed to represent a piece of data., Lossless compression algorithms are only used to compress text data., Lossless compression algorithms only allow for an approximate reconstruction of the original data.

Lossy compression algorithms are typically better than lossless compression algorithms at reducing the number of bits needed to represent a piece of data.

Which of the following is true of how computers represent numbers? Options: 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.

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

Which of the following best describes how computing devices represent information? A computer will either represent information as bits or bytes but not both, A computer represents data as a byte which is either a 0 or a 1, A computer represents data as bits which is either a 0 or a 1, A computer represents information as bits which contain 8 bytes.
