Early network interface controllers were commonly implemented on [[expansion card]]s that plugged into a [[computer bus]]. The low cost and ubiquity of the [[Ethernet]] standard means that most newer computers have a network interface built into the [[motherboard]], or is contained into a [[USB]]-connected [[dongle]], although network cards remain available.
Modern network interface controllers offer advanced features such as [[interrupt]] and [[Direct memory access|DMA]] interfaces to the host processors, support for multiple receive and transmit queues, partitioning into multiple logical interfaces, and on-controller network traffic processing such as the [[TCP offload engine]].

Modular designs like [[Small
[[LED]]s adjacent to or integrated into the network connector inform the user of whether the network is connected, and when data activity occurs.
