active or bandwidth-hogging computers and servers directly

backbone, or through a departmental switch. The 1000Mbps
Gigabit Ethernet Card also includes very large (96 KB) data

performance by virtually eliminating buffer overruns.
PCI Interface
The 1000Mbps Gigabit Ethernet Card attaches to the host
computer via the fast and efficient PCI bus. The host PCI slot
can be either 32- or 64-bit, and should be compliant with PCI
v2.1 or later. Make sure the host computer has a 64-bit PCI
bus in order to take advantage of the full-duplex speed
enhancement, otherwise, even though your connection will be
full-duplex, the traffic bottleneck at the PCI interface will
only allow half-duplex equivalent speeds.
In addition, the 1000Mbps Gigabit Ethernet Card uses the
following advanced features to maximize the utilization of
the PCI bus and reduce overhead on the system CPU:
Bus Master technology - the NIC masters the PCI bus,
freeing the CPU from PCI bus management duties.
Direct Memory Access (DMA) – enables the NIC to
write directly to the system memory, freeing the CPU
from many memory management duties.
Burst transfers – full bandwidth packet bursting across
the PCI bus increases the throughput for small packets
by coalescing transfers.
