Apple FireWire is a cross-platform of the high-speed
serial data bus that can move large amounts of data between computers and
peripheral devices. It features simplified cabling, hot swapping, and transfer
speeds of up to 800 megabits per second. Thankfully, along came FireWire and
Universal Serial Bus (USB): faster and easier to use replacements for serial and
parallel ports.
A simple common plug-in serial connector on the back of your computer and on
many different types of peripheral devices a thin serial cable rather than the
thicker parallel cable you now use to your printer, for example
A very high-speed rate of data transfer that will accommodate multimedia
applications
Hot-plug and Plug and Play capability without disrupting your computer
The ability to chain devices together in a number of different ways without
terminators or complicated set-up requirements
FireWire is integrated into Power Macs, iMacs, E-Macs, Mac-Books, Mac-Book Pro,
and the iPod. FireWire ports were also integrated into many other computer
products dating back to the Power Macintosh G3 computers. All these machines
include FireWire ports that operate at up to 400 megabits per second and the
latest machines include FireWire ports that support 1394b and operate at up to
800 megabits per second.
USB 2.0 offers several benefits such as low cost, expandability, and
auto-configuration, hot-plugging and outstanding performance. It also provides
power to the bus, enabling many peripherals to operate without the added need
for an AC power adapter. Since USB is a standard, third-party hardware is
identical for all platforms; only differing in the software required for a
specific OS.
Apple FireWire provide:-
A simple common plug-in serial connector on the back of your computer and on
many different types of peripheral devices
A thin serial cable rather than the thicker parallel cable you now use to your
printer, for example
A very high-speed rate of data transfer that will accommodate multimedia
applications (100 and 200 megabits per second today; with much higher rates
later)
Hot-plug and Plug and Play capability without disrupting your computer
The ability to chain devices together in a number of different ways without
terminators or complicated set-up requirements
How Apple FireWire Works
There are two levels of interface in IEEE 1394, one for the backplane bus within
the computer and another for the point-to-point interface between device and
computer on the serial cable. A simple bridge connects the two environments. The
backplane bus supports 12.5, 25, or 50 megabits per second data transfer. The
cable interface supports 100, 200, or 400 megabits per second. Each of these
interfaces can handle any of the possible data rates and change from one to
another as needed.
The serial bus functions as though devices were in slots within the computer
sharing a common memory space. A 64-bit device address allows a great deal of
flexibility in configuring devices in chains and trees from a single socket.
The internet is the best place to buy cheap computer parts. Due to increase in
demand for many parts in many suppliers find it profitable to sell their
products online. The online dealers have their websites, which offer information
on the various types of Mac parts available for purchase.
