Question

question 6 of 10
which statement describes lossless compression?

a. it is a method that results in the loss of all the original data in a
file.

b. it is a method that converts temporary files into permanent files
for greater storage capacity.

c. it is a technique that allows all of a files data to be restored from
compressed data.

d. it is a technique that accesses memory addresses to retrieve data.

Explanation:

To determine the correct statement about lossless compression, we analyze each option:

• Option A: Lossless compression does not result in loss of original data (that's lossy compression), so A is incorrect.
• Option B: Lossless compression is about compressing data to reduce size, not converting temporary to permanent files, so B is incorrect.
• Option C: By definition, lossless compression allows the original data to be fully restored from the compressed data, so this matches the concept.
• Option D: Accessing memory addresses is not related to lossless compression, so D is incorrect.

Answer:

C. It is a technique that allows all of a file's data to be restored from compressed data.
