Question

question 9 of 10
what is lossy compression?

a. it is a method that stores data dynamically, requiring more power.

b. it is a technique that results in the loss of all the files on a
computer.

c. it is a method of combining the memories of the ram and the
rom.

d. it is a technique that reduces file size by permanently removing
some data.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Lossy compression is about reducing file size, not storing data dynamically or power requirements. Eliminate A.
• Option B: Lossy compression does not delete all files on a computer. Eliminate B.
• Option C: Combining RAM and ROM memories is not related to lossy compression. Eliminate C.
• Option D: Lossy compression reduces file size by permanently removing some (perceived as less important) data, which matches the definition.

Answer:

D. It is a technique that reduces file size by permanently removing some data.
