A device such as a network card allows a laptop or computer to work on the Internet and a local network via WiFi, with a connection via USB or through a special cable. The adapter provides a unique address called MAC, which identifies a computer device that transmits packets of information over the network. If there is no possibility to connect with a cable, it is possible to purchase a wireless wifi-adapter for computer equipment.

What is a network card?

The hardware configuration element of a laptop or computer is called the Network interface controller, which provides the ability to connect to the network, providing interaction between devices. Network cards are LAN adapters, NICs, Ethernet adapters, or interface cards. Now the Network interface controller is part of the computer configuration, but earlier it was released separately.

Types of Network Cards

The Ethernet adapter is designed to connect computer devices to a local network. At the Network interface controller, which provides an Internet connection, the main characteristic is the data transfer speed. NIC uses high-speed interfaces to interface with a computer device. There are 4 design types of computer boards. They all have major pros and cons..

Types into which microcircuits are divided by physical implementation:

  • integrated – as the name implies, integrated into the motherboard;
  • wireless – for bluetooth and WiFi networks;
  • internal (separate cards) – are connected via PCI, inserted into the PCI-E or ISA slot;
  • external network cards for laptops – are inexpensive, connect via USB.

Why do I need a network card in a computer

The main purpose of a network card is to combine computer devices with each other. An Ethernet adapter provides Internet connectivity. If there is no built-in Network interface controller, then USB modems are used, but then the possibilities of working on the network are reduced. Combining computers, laptops, peripherals (scanners, printers, etc.) in one local network, you can exchange data via WiFi within the boundaries of the apartment, house or network provider.

Principle of operation

Part of the functionality of the Network interface controller can be transferred to a central processor or driver. Information is transmitted over the network, which is grouped into data packets. They move from one device to another. There is software and hardware involved in data transfer. NIC refers to hardware. He is responsible for establishing a physical connection between the devices. An 8-pin RJ-45 or 15-pin AUI connector is used..

Where is the network card in the computer

The network card in the computer is located in the system unit. You can find it by opening the side cover of the system unit. Modern computers do with an Ethernet interface. The built-in NIC is soldered to the motherboard. If it is not built-in, it is inserted into one of the free white slots. Functioning and data transfer is carried out using an optical fiber cable connected to the adapter connector.

What does a network card look like?

You can see how the network card looks in online stores where there are photos of devices. Externally, the device looks like a USB flash drive, and internally – a small microcircuit or board located near the computer network connection jack. It is curved on one side. If you do not open the side panel of the system unit, the location of the Network interface controller looks like a cable jack.

How to find out a computer network card

In the Windows operating system, it is not difficult to determine the NIC, which is necessary in case of a malfunction or when replacing. Programmers call such adapters consumables, because they tend to break. A network card for the PC is an important part of the system configuration, so you can use special programs such as Everest and AIDA64 to detect it. You can determine the name of the model yourself by going the way:

  1. Start.
  2. Control Panel.
  3. system and safety.
  4. System.
  5. device Manager.
  6. Network adapters.

How to check the network card for performance

A broken network card for a computer or a faulty Wi-Fi card will not allow access to the Internet or a local network. Health problems can be hidden in the system settings (if you have a built-in LAN adapter) or in the cable connection density (if external). You can try updating drivers or testing. Verification is carried out in the following way:

  1. Computer properties.
  2. device Manager.
  3. If there are no exclamation points in front of the name of your adapter, then the equipment is detected normally. Contact your provider.

How to install a network card on a computer

Before you make a decision about buying a LAN adapter, you need to make sure that the motherboard does not have its analogue. NIC can be simply disabled. To enable it, activation is required in the basic input / output system (BIOS). If it really isn’t, then buy a NIC in a computer store, and then install and connect a network card:

  1. Remove the side cover of the system unit.
  2. After choosing the free space on the motherboard, remove the plug from the back of the unit.
  3. Install NIC, fasten with fixing screw.
  4. Connect the cable to the LAN adapter.
  5. Turn on the computer. Light diodes blink, notifying about the exchange of information with the network.
  6. Configure communication: install the driver for the network card, register the server dns (dns).

Price

The adapter will cost up to $ 5. A set of functions can be selected as desired (adapter with a higher data transfer rate, 2 SFP ports). You can order a set of adapters through the catalog in specialized stores of computer equipment or buy in an online store (from 299 rubles). In the table below you will find the price of a network card in Moscow:

Title Manufacturer Cost in rubles

How to choose a network card for a computer

When buying a board, you should be guided by the criteria. The brand will be the most important. Specialists recommend well-known brands that serve for a long time. You should not save on technology and buy cheap. The right choice will ensure the functionality of the device for many years. It is easy to choose a network card for a computer if you select it in accordance with generally accepted parameters, such as:

  1. Well-known manufacturer. The leaders are Tp-link and Gembird. The best discrete adapters that last a long time are considered by Acorp and D-Link.
  2. A connector for connecting to a local network. According to the standard on the product should be indicated – 1 LAN port.
  3. Type of port. The classic connection interface is considered PCI for computers (including the oldest models), and PCMCIA may be suitable for laptops.
  4. Data transfer rate. It depends on how fast the data will load. The optimal Ethernet speed setting is 10/100 MB / Sec. There are expensive models with high price and speed support 1Gb / sec.
