A network card is understood to be the device that allows different devices to be connected to each other and that through this connection gives them the possibility of sharing and transferring data and information from one device to another. Usually, network cards are used in computing
The network card (also known as a network adapter) can be external or internal. That is, it can be inserted into the motherboard but there is also the possibility of connecting a network card to a computer externally by using the corresponding slots. These cards are very useful hardware since they allow to establish different types of connections (permanent or temporary) between one or more computers, thus facilitating the use, transfer and access to essential materials.
Different types of network cards are on the market today. Some of them are more popular than others and this has to do almost exclusively with the type of material they use as well as the efficiency of their operation. In this sense, the cards that use the Ethernet system are the most popular since they acquire higher speed than others (for example the Token Ring that are almost no longer on the market). Finally, we cannot fail to mention the increasingly popular and used Wi-Fi. This type of network card allows you to establish network connections without the need to resort to cables, so you can enjoy it anywhere and at any time as long as you have the appropriate computer (normally notebooks are prepared for it).
The network card is a communication peripheral since its function is simply to connect and communicate several devices at the same time. Each of these network cards has a unique identification number with 48 bits.
