The DGE-560T Gigabit PCI Express Ethernet Adapter is a network interface card (NIC) designed to provide high-speed network connectivity to desktop computers through a PCI Express (PCIe) slot. It supports Gigabit Ethernet speeds (up to 1000 Mbps) and is typically used to add a network connection to a computer or server, especially for environments that require fast, reliable network access.

The Windows driver for the DGE-560T allows your computer's operating system to communicate with the adapter, enabling it to send and receive data over a network.
