Which port will give you the best performance when connecting a scanner to a computer?
1. IEEE 1284
2. USB 2.0
3. Serial
4. >>IEEE 1394
Explanation : The best performance when connecting a scanner to a computer is provided by IEEE 1394 (FireWire). FireWire 1394b provides transfer rates of more than 800 Mbps. FireWire 1394a provides transfer rates up to 400 Mbps.
USB 2.0 provides good transfer rates (up to 480 Mbps for high speed USB 2.0). However, it is not as fast as FireWire.
Scanners are typically not connected through a serial interface. A serial interface provides the slowest transfer rate.
Although you can connect a scanner using a parallel connector (IEEE 1284), doing so will result in a lower transfer rate than either USB 2.0 or IEEE 1394.
