Definition of Network Card
A network card, network adapter, LAN Adapter or NIC (network interface card) is a piece of computer hardware designed to allow computers to communicate over a computer network. It is both an OSI layer 1 (physical layer) and layer 2 (data link layer) device, as it provides physical access to a networking medium and provides a low-level addressing system through the use of MAC addresses. It allows users to connect to each other either by using cables or wirelessly.

More Information on Network Cards
Ethernet is the most commonly used type of network card. Although most modern computers have built in
gigabit network cards, there are still a variety of basic and extended packages available to improve your sharing capabilities.
10 gigabit network adapters are used in state-of-the-art solutions for file sharing. Most cards also have light-emitting diodes (LEDs) to notify the user that they are connected to the
network.
The
Ethernet connection can be used for both large regions and LANs. Local area network cards are designed for a relatively smaller space for sharing such as a home or small business. Each MAC address symbolizes the
Ethernet card specific to a particular computer so the
network can distinguish between users.
Other network cards include
fiber channel, and although they are sometimes considered more efficient, they are far more costly than
gigabit or
10 gigabit cards that solve the same networking problems.
