How many pins does the IEEE 1394b connector have?

4 pins
6 pins
8 pins
9 pins

The correct answer is: 9 pins

The IEEE 1394b connector, also known as FireWire 800, has 9 pins. This is because it is designed as a 9-pin connector, with one guide pin that does not transmit any signals. Option A is incorrect because it doesn't have enough pins to match the standard. Option B is incorrect because it is the number of pins for the older version, IEEE 1394a. Option C is incorrect because it would not be able to support the high data transfer speeds that IEEE 1394b is capable of.
