A technician is tasked with adding an expansion card to connect an external device. Which of the following expansion cards would provide the FASTEST data transfer speeds?

The correct answer is A. IEEE 1394. IEEE 1394 (FireWire), specifically FireWire 800 (IEEE 1394b), supports data transfer speeds up to 800 Mbps, making it the fastest option listed. USB 2.0 tops out at 480 Mbps. RS-232 is a legacy serial standard with speeds typically under 1 Mbps. EIDE (Enhanced IDE) is a…

Explanation

IEEE 1394 (FireWire), specifically FireWire 800 (IEEE 1394b), supports data transfer speeds up to 800 Mbps, making it the fastest option listed. USB 2.0 tops out at 480 Mbps. RS-232 is a legacy serial standard with speeds typically under 1 Mbps. EIDE (Enhanced IDE) is a parallel internal bus standard used for connecting internal drives, not external devices, and is not suitable for this role. In the context of this question, IEEE 1394 provides the highest real-world throughput for external device connectivity.
