question 3 of 10
what is one trade - off of using optical discs to store files?
a. they keep data for a very long time when stored correctly but can be easily scratched.
b. the drives are more expensive than ssds, but you can read and write to them anywhere.
c. the drives are less expensive than hdds but have many moving parts.
d. they read and write data faster, but over time, the data becomes difficult to access.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Optical discs (like CDs/DVDs) can retain data for long if stored properly, but their physical surface is prone to scratches which can damage data. This is a valid trade - off.
• Option B: Optical disc drives are generally less expensive than SSDs, and also, you can't read/write to optical discs just "anywhere" without the appropriate drive, so this is incorrect.
• Option C: Optical disc drives have no moving parts (unlike HDDs which have spinning disks and moving read - write heads), so this statement is wrong.
• Option D: Optical discs are relatively slow at reading and writing compared to many modern storage options, and data access issues over time are not a typical trade - off described correctly here.

Answer:

A. They keep data for a very long time when stored correctly but can be easily scratched.
