The Intel(R) Ethernet Converged Network Adapter X550-T2 is a network interface card (NIC) that provides high-performance Ethernet connectivity, typically used in servers or high-end workstations. It supports 10GbE (10 Gigabit Ethernet) and can be used in environments requiring high-speed network access. The X550-T2 refers to a dual-port version of this adapter, providing two physical Ethernet ports for networking.

The Windows driver for this adapter allows the operating system to communicate with the hardware and enables the adapter's full functionality, including network communication, speed optimizations, and more. Intel provides specific drivers for this device for different versions of Windows (e.g., Windows 10, Windows Server 2019, etc.).
