NETGEAR 10/100/1000 Mbps CardBus Adapter GA511 User Manual
1-2
v2.0, March 2007
By utilizing internal bus speeds, CardBus can operate at speeds six times faster than a 16-bit PC
Card and five times faster than a 100 Mbps PC Card. In addition, CardBus PC cards operate at 3.3
Volts, saving power and conserving your PC's battery life.
Bus-Mastering Capability
Model GA511 features leading-edge bus-mastering capabilities to optimize throughput while
maintaining low CPU utilization. Bus mastering allows the GA511 to assume control of your PC's
system bus, accelerating data transfers. 16-bit PC Cards, by comparison, act as a bus slave and
pass data through the CPU before sending it to the host system. This slows data transfers and strain
your PC's processor.
Frame Priority Tagging for Virtual LANs
The GA511 is 802.1Q/1p-compliant for frame priority tagging. The IEEE 802.1Q standard defines
the operation of Virtual LAN (VLAN) bridges that permit the definition, operation and
administration of VLAN topologies within a bridged LAN infrastructure. Using the GA511 with
802.1p-compliant switches or routers offers a range of traffic prioritization of Layer 2 frames,
providing a higher quality of service on high-speed local area networks.
