NIC

A Network Interface Card (NIC) is hardware that connects a computer or server to a network, enabling communication and data transfer.

A Network Interface Card (NIC) is a hardware component that provides connectivity between a computer, server, or other device and a network. NICs can be integrated into the motherboard or installed as expansion cards and support wired (Ethernet) or wireless (Wi-Fi) connections.

NICs are fundamental to networking, enabling devices to communicate, share resources, and access the internet. They handle tasks such as packet transmission, reception, and error checking. Modern NICs may also support advanced features like VLAN tagging, jumbo frames, and hardware offloading for improved performance.

While standard NICs focus on basic connectivity, advanced options like SmartNICs add programmability and offload capabilities for more demanding use cases.
