What are the functions and functions of the network card

As an essential part of a computer, the network card plays an important and indifferent role in the intermediate process. Why do you say that? Because the signals between network cards are similar, the difference is not as huge as CPU, and the price is relatively cheap. But it is undeniable that the computer must use the network card if it wants to access the Internet. If it wants to get the most stable network, it must choose a good network card. Let's introduce the functions and functions of the network card.

1、 Functions of network card

The most important function of the network card is to let the computer access the Internet. How is this function realized? Listen to Xiaobian explain to you. As we all know, the network converts information into current through analog signals. The network card acts as a decoder in this. It is the responsibility of the network card to re convert the electrical signals into text and images. Other functions of the network card include monitoring the upload and download traffic and controlling the stability of the network speed. It is equivalent to the port of the computer. You should visit the network card before uploading all information to the network.

2、 Function of network card

There may be some friends who don't understand its function. First of all, it can decode to ensure that we can access the Internet. In addition, it can ensure that the network speed is stable. It is also equivalent to our network speed controller. Whether your network speed can reach the quota of the package you buy depends on whether your network card can work normally.

Today's network card technology has been very mature, and there will basically be no low network speed caused by too backward network card. Therefore, the main criteria for judging whether a network card is excellent are whether it can maintain network stability and how many data streams it can handle at the same time. A stable working frequency and excellent hardware cooperation can maintain the stability of network speed, and the processing capacity of data streams depends on the performance of the network card itself. The more data streams can be processed simultaneously by the agreed network card.

In addition, the network card of the notebook generally undertakes the task of WLAN connection. This network card will be equipped with a cellular antenna to collect signals. In addition, it can process its own network signals into WLAN hotspots for use by other electronic devices. In addition to looking at its own performance, this network card should also pay attention to the quality of the cellular antenna. The signal acceptance range of a good antenna will be wider and the network connection will be more stable.
