What is the maximum speed of IEEE 1394b?

  1. 400 Mbps

  2. 800 Mbps

  3. 1.6 Gbps

  4. 3.2 Gbps

The correct answer is: 800 Mbps

IEEE 1394b, also known as FireWire 800, has a maximum speed of 800 Mbps (megabits per second). This is twice the speed of its predecessor, IEEE 1394a (or FireWire 400), which has a maximum speed of 400 Mbps. Option A and C are incorrect because they are the maximum speeds of IEEE 1394a and 1394b, respectively. Option D is incorrect because it is the maximum speed of IEEE 1394c, which is a modified version of IEEE 1394b. Therefore, the correct answer is option B.
