PCI Express is the next revolution in I/O interconnect standards that will deliver the bandwidth and features required by PCs, consumer electronics and communications devices. 

The architecture is a cost-effective, low-pin count, and point-to-point technologies offering maximum bandwidth, reducing cost and design complexity and enabling smaller form factors. 

This card is the best solution for Gigabit Ethernet PCI Express and the interface has a potential transfer rates of 2.5 Gbps using a four-lane (or x4) PCI Express link.

This card is a 4-Port Gigabit Ethernet PCI Express Card, which is specifically designed to plug into a desktop equipped with an available x4, x8 or x16 PCI Express slot. 

It comes with a comprehensive of software drives for all desktop operating systems, including Microsoft Windows and Linux.
