Final answer:
The IEEE 1394B standard, also known as FireWire 800, offers higher data transfer rates of up to 800 Mbps, longer cable lengths up to 100 meters with optical fiber, and improved hardware with better shielding compared to the IEEE 1394A standard, which has lower data rates and shorter cable length limitations.
Step-by-step explanation:
Differences between IEEE 1394A and IEEE 1394B Standards
The Institute of Electrical and Electronics Engineers (IEEE) 1394 standard is a serial bus interface standard known as FireWire, used for high-speed communication and isochronous real-time data transfer. The IEEE 1394A is the original version, which supports data transfer rates of 100, 200, or 400 Mbps. On the other hand, the IEEE 1394B standard, which is also known as FireWire 800, represents an enhancement of the previous standard. It increases performance and extends the range of physical media types it can use.
One of the main differences is the introduction of new data rates, which includes 800 Mbps, double the maximum rate of the original version. Additionally, IEEE 1394B supports longer cable lengths of up to 100 meters through the use of optical fiber, whereas IEEE 1394A is limited to a maximum cable length of 4.5 meters when using copper. IEEE 1394B also includes improved hardware with the introduction of newer connectors and better shielding, resulting in improved noise immunity and making it better suited for professional and industrial environments.
