What is the maximum data transfer rate of an IEEE 1394a device?

400 Mbps
800 Mbps
1 Gbps
100 Mbps

The correct answer is: 400 Mbps

The maximum data transfer rate of an IEEE 1394a device is 400 Mbps. This specification pertains to the FireWire standard, which was prevalent in certain multimedia and data transfer applications. IEEE 1394a supports this speed under normal operating conditions, making it suitable for high-speed data communication tasks such as connecting video cameras, hard drives, and other peripherals. While there are higher versions of FireWire, such as IEEE 1394b, which can achieve speeds up to 800 Mbps, the question specifically focuses on the IEEE 1394a standard and its characteristics. The other data rates listed do not apply to this version of the standard; hence, the most accurate representation for IEEE 1394a remains at 400 Mbps.
