Explanation:
Up to 63 IEEE 1394 devices can be connected to a single IEEE 1394 port through daisy-chaining.
Institute of Electrical and Electronics Engineers (IEEE) 1394 is a standard for high-speed serial bus
that provides enhanced PC connectivity for
a wide range of devices. These devices include consumer audiovisual components, traditional PC
storage devices, and handheld devices. IEEE
1394 is also known as Firewire.
The FireWire connector is used with the FireWire serial bus. FireWire can transmit data at a very
high speed of 400Mbps and 800Mbps. Two
types of connectors are available in this category, namely 4-pin and 6-pin.
