Network Interface Card (NIC)
Network Interface Card (NIC) is a hardware component that is present on the computer. It is used to connect different networking devices such as computers and servers to share data over the connected network. It provides functionality such as support for I/O interrupt, Direct Memory Access (DMA) interfaces, partitioning, and data transmission.
NIC is important for us to establish a wired or wireless connection over the network.
Network Interface Card is also known as Network Interface Controller, Network Adapter, Ethernet card, Connection card, and LAN (Local Area Network) Adapter.
Functions of the Network Interface Card
A list of functions of the Network Interface Card is given below -
Components of Network Interface Card
Network Interface Card contains the following essential components -
Memory is one of the most important components of the NIC. It is used to store the data during communication.
connectors are used to connect the cables to the Ethernet port.
Processor is used for converting the data message into a suitable form of communication.
Jumpers are the small device that is used to control the communication operations without the need of any software. It is also used to determine settings for the interrupt request line, I/O address, upper memory block, and type of transceiver.
To provide wireless connectivity, routers are used.
6. MAC address
MAC address is also referred to as a physical network address. It is a unique address that is present to the network interface card where ethernet packets are communicated with the computer.
Types of Network Interface Cards
There are the following two types of NICs -
1. Ethernet NIC
Ethernet NIC was developed by Robert Metcalf in 1980. It is made by ethernet cables. This type of NIC is most widely used in the LAN, MAN, and WAN networks.
Example: TP-LINK TG-3468 Gigabit PCI Express Network Adapter.
2. Wireless Networks NIC
It is a wireless network that allows us to connect the devices without using the cables. These types of NICs are used to design a Wi-Fi connection.
Example: Intel 3160 Dual-Band Wireless Adapter
