Which of the following is true of lossy and lossless compression algorithms?
Your answer:

A. Lossy compression algorithms are used when perfect reconstruction of the original data is important,
B. Lossy compression algorithms are typically better than lossless compression algorithms at reducing the number of bits needed to represent a piece of data.
C. Lossless compression algorithms are only used to compress text data,
D. Lossless compression algorithms only allow for an approximate reconstruction of the original data.

Answer 1

Step-by-step explanation:

Keep in mind a lossy algorithm will lose information while a lossless algorithm maintains all your original information.

Therefore:

A. False, a lossy algorithm will not allow perfect reconstruction.

B. True, if you don't care about keeping all your information it's easier to compress.

C. False, you can use a lossless algorithm for anything.

D. False, the point of lossless is that you keep all information.
