Electronic devices which may contain evidence includes which of the following?

• A. Wearable tech
• B. Televisions
• C. CDs, DVDs, Blue-ray disks
• D. USB drives

Answer: (C)

Digital evidence often lives on physical media that can hold substantial data in a portable, removable form. Optical discs—CDs, DVDs, and Blu-ray disks—are classic sources because they can store large amounts of information such as documents, photos, videos, and backups, and they’re commonly found in many investigative settings. When collected properly, these discs can be imaged bit-for-bit with a write-blocker, preserving the original data exactly as it existed, which makes them highly reliable for proving what was on them. Wearable technology and televisions can contain data, but they’re less universally reliable as evidence sources. Wearables vary widely in what they store and how accessible it is, and televisions often rely on external devices or streaming data rather than storing extensive information themselves. USB drives are indeed common repositories too, but the question highlights optical media as a particularly typical and enduring source of evidentiary material.
