The network adapter is the link between the computer and the network. This device can replace the network card if it is not in the computer or if the internal card does not support the required standard.
What are the network adapters
There are two main types of network: wireless and wired. Network adapters can be used with both types of network. At the same time, there are more network adapters for wireless networks, since there are more varieties of such networks.
A computer with an adapter can be connected to a network using a cable. For wired networks, a device is used, which is a USB key with a special port for an Ethernet cable. This cable can connect, for example, a router and an adapter.
The adapter may come with software, but most modern operating systems recognize the USB adapter and find the drivers necessary for it to work.
But most often, a network adapter means a device for wireless networks. Such adapters are popular for their portability. They allow the computer to join a nearby wireless network.
The wireless network adapter resembles a memory card or flash drive. This is a small USB device with a flashing light to indicate that it is charged and ready for use. When connected to a computer, it scans the Internet channels of local providers and informs the computer software of the presence of networks. The computer, in turn, shows these networks to the user. In order for the computer to connect to the network of interest, just click on its name and enter the password, if required. The next time you turn it on, your computer will automatically connect to this network.
Many computers today have wireless network adapters already integrated into the machine. They are microchips.
Finally, there are the network adapters, which are purely software. They simulate the functions of a network card. These are called "virtual network adapters".
Why do you need network adapters
Most laptops have a built-in wi-fi or wireless network card. But sometimes this card doesn't work. This is especially true when wireless networking standards change to a newer and faster connection protocol. Then old cards that support outdated protocols will not work with a router that supports the new standard.
When buying a new network adapter, you should pay attention to the protocol it supports. This small and useful device can be found in any Hi-Tech store.
When the internal NIC does not support the new standard, a new NIC can be an alternative to the NIC. It is easy enough to replace it on a desktop computer. But in laptops and laptops, this is much more difficult to do. In such cases, it is more convenient to use a network adapter.
