LevelOne Gigabit PCI Network Card 550022 Fiche De Données

Thank you for choosing LevelOne 10/100/1000Mbps Gigabit Ethernet Card for 32-bit PCI Bus-

equipped personal computers. The 32-bit PCI 10/100/1000Mbps Gigabit Ethernet Card is ideal for 

speeding up data transfers for network servers and other computers, such as those used for video-

conferencing, that send and/or receive large amounts of data. The 32-bit PCI 10/100/1000Mbps 

Gigabit Ethernet Card also includes the newest networking technologies, such as multicasting support, 

that use network bandwidth more efficiently and further help the card maximize data throughput.

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, 

and support for CSMA/CD protocol, full duplex, and management objects, but with a tenfold increase 

in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps 

Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet 

provides a straightforward upgrade without wasting a company’s existing investment in hardware, 

software, and trained personnel. 

The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to coping with the 

network bottlenecks that frequently develop as computers and their busses get faster and more users 

use applications that generate more traffic. Upgrading key components, such as your backbone and 

servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed 

up the traffic between your subnets. 

Gigabit Ethernet enables Twisted-Pair cable connections to support video conferencing, complex 

imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster 

than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the 

number of operations in the same amount of time.
