I/O (Input / Output) Bus - Peripheral
Pathway circuitry connecting Peripheral
Devices to the CPU for moving data. Whereas the CPU & Memory connect
through the System Bus a.k.a. Front Side Bus (FSB), which is faster than
the I/O Bus.

- Azalia - Intel's next generation High
Definition Audio program codenamed Azalia.
- Intel kicks off nex-gen audio effort: "Azalia codecs
sit on a dedicated bus that links to dedicated audio, telephony or
communications devices. The bus runs at a selectable 3.3-1V. It
supports 24 Mbit/second audio inputs and "double-pumped"
48 Mbit/second audio output." (5/19/2003).

Architecture) Bus Interface: (CAT5) Gigabit Ethernet
- Fibre Channel
Technology: One and Two Gigabit Interconnect Technology!
I/O Interconnect - Server I/O Interconnect
Server I/O Bus Architecture expected
to replace PCI Bus. InfiniBand is a combination of Intel's NGIO (Next
Generation I/O) and Future I/O from IBM, HP and Compaq. In 2000,
Future I/O and NGIO merged into one technology, originally named
System I/O and now InfiniBand with currently 100 Companies behind its
InfiniBand is a Serial,
Point-to-Point Switching Architecture suitable for Data Center
Bandwidth requirements capable of 500 MBps to 6 GBps
between two Nodes.
- Parallel ATA/ATAPI
- PCI Technology:
Express - The next Desktop I/O Bus Interface
on the horizon expected to replace PCI Local Bus architecture. Due out
in 2004 (5/28/2003).
- Specifications - PCI-X
- Parallel Port - IEEE 1284:
A connection point on a computer to connect Devices passing data into
and out of a computer. A printer is typically connected to a Parallel
Port (also called an LPT Port), and a Dial-Up
Modem is typically connected to a Serial Port (also called a COM
Port). IEEE 1284 also defines required cable type and increases
distance to 32 feet. Considered a Legacy Device.
The DirectParallel feature in Win2000
supports computer-to-computer connections by using standard and
enhanced (ECP) Parallel Ports, which use Parallel Technologies'
Basic or Fast parallel cables. For information about configuring a
direct network connection to use a DirectParallel cable, see To make a
direct network connection by using a DirectParallel cable. Direct
Cable Connection cables are available from several sources. You can
obtain DirectParallel cables from Parallel Technologies or from their

(Enhanced Parallel Port) mode increases bi-directional
transfer from the Centronics 150 Kbytes/sec to between 600
Kbytes/sec and 1.5 Mbytes/sec. Nibble and byte modes provide
(Enhanced Capabilities Port) designed for Printers.
and Serial Technologies: "The
recommended implementation for I/O connections on new PCs and for
new devices is to use USB or IEEE
1394. However, Microsoft Windows Operating Systems continue to
support legacy Serial and Parallel Ports and devices. However,
Microsoft does not provide parallel drivers for 64-bit
versions of Windows."

- Small Computer System Interface.
ATA - High Speed Serialized AT Attachment.
- Serial Port:
A Computer Port allowing asynchronous transmission of data characters
one bit at a time. Also called a Communications or COM Port.
Considered a Legacy Device.
System Management Bus (SMBus) defined by Intel in 1995.
It is used in Personal Computers and Servers for low-speed System
Universal Serial Bus
