PCI Network Adapter

A PCI Network Adapter is a hardware device that enables a computer to connect to a network via a physical connection such as Ethernet, fiber optic, or InfiniBand. It is installed into an available PCI slot on the motherboard of a desktop or server computer, and typically consists of a small printed circuit board with one or more network ports.

The PCI Network Adapter allows a computer to communicate with other devices on the same network, including other computers, servers, printers, and storage devices. It provides the necessary physical layer and data link layer functionality to transmit and receive data over the network.

PCI Network Adapters are available in various speeds ranging from 10 Mbps to 100 Gbps, and may support various network protocols such as TCP/IP, UDP, and ICMP. They may also offer advanced features such as Quality of Service (QoS), VLAN tagging, and virtualization.

PCI Network Adapters are widely used in enterprise networks, data centers, and cloud computing environments to connect servers and other network devices to the network. They are often preferred over onboard network interfaces on the motherboard due to their faster speeds, better performance, and ability to support more advanced networking features.
