If you are interested in pictures recovery, see: Recover Deleted Pictures on Mac FireWire is a standard connection type for many different kinds of electronic devices such as digital video cameras, external hard drivesand other peripherals.

The terms IEEE and FireWire usually refer to the types of cables 1394 USB Optical Disk are used to connect these types of devices to computers. The most common copper cable of the FireWire can be up to 4. This cable also carries power, allowing devices with medium power requirements to operate without a separate power source. It is also available in Cat 5 and fiber versions.

It can transmit data ator Mbps, depending on the FireWire cable. These data transmission modes are commonly referred to as S, 1394 USB Optical Disk and S It has six circuits, two of which provide power to the device.


It is most commonly used on desktop computers. This version of FireWire is designed to improve the original design. It provides faster bus reconfiguration, power-saving suspend mode and more. 1394 USB Optical Disk is capable of both asynchronous and isochronous transfer methods at once. Isochronous data transfers are transfers for devices that require continuous, guaranteed bandwidth. All these elements require constant, uninterrupted bandwidth. To support both elements, FireWire dedicates a certain percentage to isochronous data and the rest to asynchronous data.

This repeats until all the devices have used their portion of the microseconds, with isochronous 1394 USB Optical Disk having priority. Cable length is limited to 4. The 6-conductor connector is commonly found on desktop computers, and can supply the connected device with power. The 6-conductor powered connector, now referred to as an alpha connector, adds power output to support external devices.

Glossary of Terms – What Is FireWire

Typically a device can pull about 7 to 8 watts from the port; however, the voltage varies significantly from different devices. Apple's implementation on laptops is typically related to battery power and can be as low as 9 V.


It added 1394 USB Optical Disk for asynchronous streamingquicker bus reconfiguration, packet concatenationand a power-saving suspend mode. It also allows for arbitrated short bus reset, in which a node can be added or dropped without causing a big drop in isochronous transmission. The 4-conductor connector is fully data-compatible with 6-conductor alpha interfaces but lacks power connectors.

This specification and corresponding products allow a transfer rate of It is backwards compatible with the slower rates and 6-conductor alpha connectors of FireWire A bilingual cable allows the connection 1394 USB Optical Disk older devices to the newer port. InApple was the first to introduce commercial products with the new connector. This gives the packet the ability to have at least two 1s, ensuring synchronization of the PLL at the receiving end to the correct bit boundaries for reliable transfer. While 8-bit symbols can encode a maximum of values, bit symbols permit the encoding of up to Symbols invalid for 1394 USB Optical Disk current state of the receiving PHY indicate data errors.

The 6-pin IEEE port also provides power to the connected device. As a result, an alternate source of power is unnecessary on certain external hard drives equipped with the 6-pin IEEE port.


A 6-to-6 pin cable is needed to connect these external hard drives to the computer. Currently the fastest IEEE port, it is often used on high-end external hard drives. The 9-pin IEEE b port it is physically smaller than the 6-pin port and isn't used very widely at the moment.
