CompTIA A+ Core 1 (220-1001) — Question 330

Which of the following is a data transfer standard that transfers 16 bits of data at a time to hard disks?

Answer options

• A. IDE
• B. USB
• C. SATA
• D. FireWire

Correct answer: A

Explanation

IDE is the correct answer because it is specifically designed to transfer 16 bits of data at once to hard disks. USB, SATA, and FireWire do not have this specific capability, as USB and FireWire support various data transfer rates and protocols, while SATA primarily focuses on higher speed data transfers without the limitation of 16-bit transfers.
