Question

many digital picture formats use data compression to accomplish which of the following goals?
a. save space on a hard drive.
b. provide a crisp and clear image.
c. eliminate redundant data.
d. produce a file that can be emailed or posted on the internet.

Explanation:

Data compression works by removing redundant or non-essential data from a file. Saving hard drive space (a) and enabling easier sharing via email/internet (d) are secondary benefits of this core function, while image clarity (b) is not a goal of compression (some compression can even reduce clarity). The direct, primary goal addressed by data compression is eliminating redundant data.

Answer:

c. Eliminate redundant data.
