Introduction
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital
audio signals to a device without having to be converted first to an
analog format. This prevents the quality of the audio signal from
degrading whenever it is converted to analog. S/PDIF is usually
found on digital audio equipment such as a DAT machine or audio
processing device. The S/PDIF connector on the system board sends
surround sound and 3D audio signal outputs to amplifiers and
speakers and to digital recording devices like CD recorders.
Serial ATA Interface
Serial ATA is a storage interface that is compliant with SATA 1.0
specification. With speed of up to 1.5Gbps, it improves hard drive
performance faster than the standard parallel ATA whose data
transfer rate is 100MB/s.
IrDA Interface
The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices. The
IRDA (Infrared Data Association) specification suppor ts data
transfers of 115K baud at a distance of 1 meter.
USB Ports
The system board supports USB 2.0 and USB 1.1 ports. USB 1.1
supports 12Mb/second bandwidth while USB 2.0 supports 480Mb/
second bandwidth providing a marked improvement in device
transfer speeds between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.
AGP (Accelerated Graphics Port)
AGP is an interface designed to support high performance 3D
graphics cards. It utilizes a dedicated pipeline to access system
memory for texturing, z-buffering and alpha blending. The AGP slot
supports AGP 8x (0.8V) with up to 2.13GB/sec. bandwidth and
AGP 4x (1.5V) with up to 1066MB/sec. bandwidth for 3D graphics
applications. AGP in this system board will deliver faster and better
graphics to your PC.
