What is the difference between the USB 2.0 and IEEE 1394 bus standards?
The correct answer is C. IEEE 1394 is slower than USB 2.0.. IEEE 1394 (FireWire) is slower than USB 2.0 in terms of maximum theoretical data transfer rates, with IEEE 1394 offering 400 Mbps compared to USB 2.0's 480 Mbps.

Why each option
IEEE 1394 (FireWire) is slower than USB 2.0 in terms of maximum theoretical data transfer rates, with IEEE 1394 offering 400 Mbps compared to USB 2.0's 480 Mbps.
IEEE 1394 (FireWire 400) is slower than USB 2.0, which achieves 480 Mbps.
Both IEEE 1394 and USB 2.0 support hot-swapping, so this is not a distinguishing difference.
IEEE 1394 (FireWire 400) has a maximum data transfer rate of 400 Mbps, whereas USB 2.0 (High-Speed USB) has a maximum theoretical data transfer rate of 480 Mbps, making USB 2.0 generally faster. This difference in speed can be significant for data-intensive applications.
Both USB 2.0 and IEEE 1394 support the Plug and Play feature, so this is not a distinguishing difference.
