A network interface controller (NIC, also known as a network interface card, [3] network adapter, LAN adapter and physical network interface [4]) is a computer hardware component that connects a computer to a computer network. [5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
NC-SI, abbreviated from network controller sideband interface, is an electrical interface and protocol defined by the Distributed Management Task Force (DMTF). The NC-SI enables the connection of a baseboard management controller (BMC) to one or more network interface controllers (NICs) in a server computer system for the purpose of enabling out-of-band system management.
Super Micro Computer, Inc., doing business as Supermicro, is an American information technology company based in San Jose, California.The company is one of the largest producers of high-performance and high-efficiency servers, [2] while also providing server management software, and storage systems for various markets, including enterprise data centers, cloud computing, artificial intelligence ...
A wireless network interface controller may be implemented as an expansion card and connected using PCI bus or PCIe bus, or connected via USB, PC Card, ExpressCard, Mini PCIe or M.2. The low cost and ubiquity of the Wi-Fi standard means that many newer mobile computers have a wireless network interface built into the motherboard.

Furthermore, it is possible to simulate several virtual NICs by implementing virtual miniport drivers that send and receive traffic from a single physical NIC. One example of virtual miniport driver usage is to add virtual NICs, each with a different VLAN. Because implementations cannot assume that other drivers received the same buffers, one ...
In non-promiscuous mode, when a NIC receives a frame, it drops it unless the frame is addressed to that NIC's MAC address or is a broadcast or multicast addressed frame. In promiscuous mode, however, the NIC allows all frames through, thus allowing the computer to read frames intended for other machines or network devices.
