It is a peripheral device that can be known by many names, among them they are apart from Network card, network interface card, network adapter, or it can also be identified as NIC which means (Network Interface Card). Which is a peripheral with which you can achieve the connection of different equipment with each other, so that there can be communication between them and in this way it is possible to share information between the terminals that are connected.
This device can be connected directly to the motherboard of the computer that would be an internal network card, and now thanks to the advancement of technology the network card can also be connected to one of its external ports. The objective of a network adapter is to ensure that computers are integrated into a network and thus different types of data can be exchanged such as information, documents, applications, Internet connection, or even others with other types of hardware such as a printer.
With the advancement of technology, new capabilities of computers have also emerged to transmit data through the network in a faster and more efficient way, in the same way network cards have adapted to the need, modifying the ports to faster transmission, one of the most used during the first decade of the XXI century were the Ethernet NICs that allowed data communication at high frequencies.
At present, network cards integrate the possibility of connecting computers to the network through wireless configurations popularly known as Wi-Fi, its fame is due to the great capacity to upload and download information without the need for extra cables. For connection to the main network, it is enough with a wireless router that transmits the network signal in Wi-Fi waves and these NICs take it with their receiving antennas, allowing large accumulations of data in a short time. Network cards with Wi Fi have made a significant leap from computers to other more portable devices such as cell phones (smartphones) and tablets.
