External flash memory has become a popular way to move large files between devices. What is the most common interface used to connect external flash memory devices?
A) Serial
B) eSATA
C) USB
D) FireWire
The answer: C) USB
The Universal Serial Bus is becoming more universal all the time. If you have a flash memory device, then it almost certainly has a USB interface.
The incorrect answers:
A) Serial
Serial connections are low-speed interfaces that run too slowly to connect storage devices.
B) eSATA
eSATA is a high-speed external interface based on the SATA interface. Although many hard drives can support external SATA connections, flash drives run too slowly to take advantage of the higher eSATA speed.
D) FireWire
FireWire, or IEEE 1394, has a number of speed and throughput advantages, but the interface type isn’t included on enough computers to provide the portability needed by flash storage devices.
