What IEEE standard is better known as Firewire 400?

IEEE 1394a
IEEE 1394b
IEEE 802.3
IEEE 802.11

The correct answer is: IEEE 1394a

Firewire 400 is commonly associated with the IEEE 1394a standard. This standard enables high-speed data transfer rates of up to 400 Mbps and is primarily used for connecting digital devices such as cameras, external hard drives, and other peripherals. Firewire technology was particularly popular in the early 2000s for its ability to provide a peer-to-peer connection, allowing devices to communicate without the need for a host computer. The other options refer to different standards that serve entirely different purposes. IEEE 1394b, for example, provides enhanced capabilities over 1394a, such as increased speed (up to 800 Mbps), but it is not referred to as Firewire 400. IEEE 802.3 pertains to Ethernet networking standards and focuses on wired local area networks, while IEEE 802.11 encompasses wireless networking standards, commonly known for Wi-Fi. These standards are distinct and do not relate to the Firewire technology, which is specifically designed for high-speed data transfer.
