FireWire

FireWire is a serial data input/output technology developed
by Apple Computer and Texas Instruments. The first FireWire
standard was approved by the Institute of Electrical and
Electronic Engineers (IEEE) in 1995.
Data transfers at up to 400 Mbps (50 MB/s)
FireWire 400 can transmit data at up to 400 Mbps (50 MB/s).
FireWire supports both isochronous and asynchronous data
transfers. Isochronous mode provides guaranteed transmission
of data at defined intervals; it's used when delayed or out-
of-order data frames are unacceptable, such as for capturing
digital video. In asynchronous mode, the intervals between
transmissions can vary, and data can be resent if missed.
Asynchronous mode is used for routine data transfers.
Supports up to 63 devices
FireWire devices can be linked in a daisy-chain, where the
devices are connected to each other in series. A hub is only
required when a very large number of devices will share the
same FireWire bus. With the use of FireWire hubs, up to 63
devices can be linked on a single FireWire bus.
Peer-to-peer architecture
FireWire devices are host-independent, meaning data
transmissions between FireWire devices on the same bus
can take place without the need for input from the host
