A network card, also known as a network interface card (NIC) or a network adapter, is a hardware component that connects a computer or other device to a network. It provides a physical interface between the computer and the network, allowing the device to communicate with other devices on the same network.

A network card typically plugs into a computer's motherboard or connects to it through an expansion slot, and has one or more ports for network cables. The card converts the data from the computer into a format that can be transmitted over the network and vice versa. Network cards can support a variety of different network protocols and speeds, depending on the specific model.

Features of Network Cards

The features of a network card, also known as a network interface card (NIC) or network adapter, can vary depending on the specific model and type. 


Network cards can support various network speeds, including 10 Mbps, 100 Mbps, and 1 Gbps or higher. The speed of the network card determines the maximum data transfer rate between the device and the network.


Network cards typically connect to a computer or device through a wired interface, such as Ethernet or fiber optic cable. Some network cards also support wireless connections, such as Wi-Fi or Bluetooth.

Protocol Support: 

Network cards can support various network protocols, including TCP/IP, IPX/SPX, and NetBEUI. The protocol support determines the type of network that the card can connect to and communicate with.

Duplex Mode: 

Network cards can operate in either half-duplex or full-duplex mode. In half-duplex mode, the network card can only transmit or receive data at one time, while in full-duplex mode, it can transmit and receive data simultaneously.


Some network cards support Wake-on-LAN, which allows a computer to be remotely powered on over the network. This feature is often used in remote management and monitoring applications.

VLAN Support: 

Network cards can support virtual LANs (VLANs), which allow a single physical network to be divided into multiple logical networks. VLAN support can be useful for segmenting traffic and improving network security.

Quality of Service (QoS) Support: 

Network cards can support QoS, which allows network traffic to be prioritized based on specific criteria. This feature is often used to ensure critical applications, such as video streaming or VoIP, receive sufficient bandwidth and minimize latency.
