What is a network card?

So, what is a network card? A network card is part of the computer's hardware configuration. This device allows us to connect the computer to the network and provides interaction with it. Network cards are often referred to as network interface cards, network adapters, or LAN adapters.

Network cards were originally an additionala component that could be purchased and installed on a computer not immediately, but after a while. However, to date it has become obvious that network cards are the standard component of a computer that is installed in most laptops and computers sold.

Often, they are integrated into motherboards orOther devices are still in production. If the card is installed in a computer system, it detects itself when connecting to the network with small flickering LEDs, which are located at the network connector.

Identification of the network card

Any network card must be unique,so they are equipped with an address that is abbreviated MAC. With it, you can identify any computer that transmits data over the network.

What is a wireless network card?

In our time, with the help of network cards, you canconnect computers using a cable (physical) connection, or even do without it, using the so-called wireless interface. Using a cable connection, usually choose a standard network port, which has a connector format "RJ-45". For wireless connection to the network, the use of various physical ports and interfaces is not required.

The principle of the wireless card is quite simple. A wireless modem is responsible for receiving and transmitting data from the Internet. The data from your provider will go to the external port (cable entry) of the wireless router, after which they will be converted into a radio signal, which will be broadcasted via the antenna. If the wireless network cards are in the field of the router's transmitter, they will receive a signal, and then convert it into an electronic, computer-understandable signal.

In any case, except that the wirelessthe network card does not require physical contact with it, its configuration does not differ from the usual one. Both wireless and wired cards now allow the development of almost the same data rate.
