The primary function of a network interface card (NIC) is to provide a physical link to a computer network. This connection allows computers to communicate with servers, as well as other computers on the network. Each NIC 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.

The network interface controller (network adapter) is the device that allows your computer to connect to the internet. It allows communication between devices using internet protocols and their addresses (IP) (IP address).

Although they can be used as an expansion card in older computers, most newer motherboards have integrated networking.

Just a note, the NIC does not allow wireless networking, only wired (ethernet) connections. You would need a WLAN card to achieve wireless networking.
