The NVIDIA Network Bus Enumerator is a virtual network device driver that is typically installed along with NVIDIA's software packages, particularly those related to NVIDIA's networking hardware or NVIDIA's GeForce Experience and CUDA drivers.

While it is not as widely recognized as traditional network adapters like Ethernet or Wi-Fi drivers, it serves a role in managing certain aspects of networking, especially when NVIDIA's software components are involved in tasks such as virtual GPU management, streaming, or gaming network optimization.
