How does the cable length of IEEE 1394a compare to typical USB cable lengths?

  1. Longer

  2. Shorter

  3. The same

  4. Varies too much to say

The correct answer is: Shorter

USB cable lengths are usually shorter than IEEE 1394a cable lengths. USB cables can range from 0.2 to 5 meters, while IEEE 1394a cables can range from 4.5 to 72 meters. Option A is incorrect because it states that IEEE 1394a cables are longer, which is not true in most cases. Option C is also incorrect because, as stated, USB cable lengths are typically shorter than IEEE 1394a cable lengths. Option D is too vague and does not provide an accurate comparison between the two cable lengths.
