What is the function of a Network Card?

Author cavsi Category: Networking Tags:

The primary function of a network interface card is to provide a physical link to a computer network. A network card is the physical interface between the computer and the network cable. It converts the data sent by the computer into a form which can be used by the network cable, transfers that data to another computer and controls the dataflow between the computer and cable.

This connection allows computers to communicate with servers, as well as other computers on the network. It also translates the data coming from the cable into bytes so that the computer’s CPU can read it.

Each network card has a unique serial number, which is called a MAC address. Every computer connected to the network is required to have a unique MAC address that is stored on the network interface card. If you are building a home network or utilizing broadband Web access, your network card or NIC connects you to the outside world.
