networking, and more than 32 channels of digital mixing. Gone are those days of expensive video capture cards. Firewire allows for video
capture from both newer DV camcorders with Firewire ports and older analog equipment using A/V to Firewire converters.
The advantages of the IEEE1394:
High data transfer rate – Start from 400 Mbps, (with 800/1600/3200 Mbps coming soon), which is about 30 times faster than USB 1.1.
Supports up to 63 devices (16 - daisy chained) with cable length up to about 4.5 m (14 feet).
Hot-pluggable (like USB). No need to turn of your device to connect or disconnect, and you don't need to reboot your PC. Also, it is a
plug-and-play bus.
IEEE1394 is very easy to connect (Like USB1.1/2/0).

The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated, parity bit will
be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the parity error is occurred
and this is called single bit error detection.

Developed by Intel, Peripheral Component Interconnect (PCI) is a local bus standard. A bus is a channel used to transfer data to (input) and
from (output) a computer and to or from a peripheral device. Most PCs have a PCI bus usually implemented at 32-bits providing a 33 MHz
clock speed with a throughput rate of 133 MBps.
