You have a customer who must perform a number of high-speed data transfers between her laptop and several different servers on a regular basis as part of her job. Traditionally, she has used USB 2.0, but she asks you if she should be using FireWire 800 instead. What do you tell her?

A. You tell her that USB 2.0 has a higher data transfer rate than FireWire 800 (IEEE 1394) and USB is more common on laptops than FireWire.

B. You tell her that FireWire 800 has a higher data transfer rate than USB 2.0 and FireWire connections are more common on laptops than USB 2.0 connections.

C. You tell her that parallel SCSI has higher data transfer rates than either USB 2.0 or FireWire 800 and this standard has been implemented on all new laptops.

D. You tell her that while FireWire 800 has higher data transfer rates than USB 2.0, FireWire ports are less common on laptops than USB 2.0 ports.

Solution

Answer:

Option D is correct

---------------------------------------------------------------------------------------------

D. FireWire 800 is significantly faster than USB 2.0, but not all PCs and laptops use the FireWire standard as commonly as they do USB 2.0.
