Network cards for computers: what the modern PC equipment market can offer. What is a network card or network adapter?
LAN card computer (Ethernet adapter, Network adapter) is needed in order to receive an Internet signal. May be built into motherboard and removable. Knowing the brand of the network card is necessary to replace it or install drivers. We will tell you where to find your computer's network card in this article.
The easiest way to find out the Internet adapter and not harm your computer is through Device Manager. You can enter it different ways. Let's look at the fastest one first. So, double-click on the “Computer” icon on the desktop or go through the “Start” menu to the same section. A window opened with hard drives. We are not interested in them now. We look up the screen to the blue stripe. We see buttons, including “System Properties”, click it. A system information window appears, by examining which you will learn about the main characteristics of your computer. Now click on the “Device Manager” button located in the left top corner. The treasured window has opened where you can see all the computer parts.
Appearance of a classic adapter
Physically, the adapter is a board with microcircuits and connectors. Despite the fact that many modern models These devices are integrated into the motherboard and, in fact, represent a set of chips and a connector located in a convenient place; they still continue to be called cards. There are also names such as network adapter and network card. The device is able to convert the electrical signal coming from the connected cable into data that the computer can understand.
How network cards work
The adapter is located at the second, data link layer of the OSI model. In order for the operating system to know how to interact with the network card, driver installation is required. They are usually supplied with the device or are available on the manufacturer's official website. Many Windows versions are able to pick up adapters installed in the system without installing additional drivers. As for Linux distributions, then almost all of them are able to work with the adapter out of the box.
Why do you need a network card in a computer, and how does it work? When receiving data, the card receives a set of signals, as a result of which it converts it to a certain sequence of bits. Then there is a check checksum this piece of data. If it matches, then they are placed in RAM. If not, they are discarded and an error is reported. When transferring data to the cable, all steps are performed in reverse order. It is worth noting that network adapter manufacturers, in order to make them less expensive, shift many tasks onto the shoulders of drivers. In server solutions, network cards may have own processor, which is itself responsible for processing, encrypting and converting signals.
A little educational background: OSI is a generally accepted model and international standard according to which protocols and devices are developed. It has 7 levels, each of which implements its own task. A short list of them looks like this: physical (cables, radio channels), channel (network cards, DSL), network (routers), transport ( TCP protocols, UDP), session (exchange and maintenance information flows), representation (data transformation), applied ( HTTP protocols, FTP, bitTorrent).
Main characteristics of network cards
The adapters have quite a lot of characteristics. But for home use most of them are useless. Therefore, let’s consider those points that, one way or another, significantly affect the price and scope of use:
- baud rate. Almost everything modern devices, even those that cost 500 rubles can support a transfer speed of 1 Gigabit. Therefore, there is no significant difference here. However, it is worth paying attention to this parameter;
- interface or connection type. This is how the network card will connect to your computer. There are currently three dominant connection types on the market: USB, PCI and PCI-E;
- number of RJ-45 connectors. If you plan to use a computer to transmit the Internet over the next link of the network, or you simply need a local network, then you should take a closer look at models that have 2 or more connectors on board;
- card profile. There is a misconception that a low profile card, or Low Profile, means it only takes up one slot. This is wrong. Low profile in networking as well as video cards means the width of the board. Speaking in simple words, this is the height of the map above motherboard. Although almost all network cards are low-profile, if there is not enough space inside the system unit, you need to choose a device with the Low Profile mark.
All other characteristics are not so important, and in most cases they can be neglected.
Types of network cards by connection method
Previously, we touched a little on the topic of connecting adapters. Let's look at it in more detail. All such devices can be divided into three large types: integrated, internal and external.
Integrated or built-in
Probably the most common type. They are chips mounted on the motherboard. Accordingly, on back panel All necessary connectors have been installed. Most modern motherboards come with this type of network adapter. It is worth noting that Wi-Fi modules are also network cards for a computer, however, they are usually called that way - “ Wi-Fi module", of course, if it is not integrated.
Internal PCI and PCI-E network cards
These devices are separate boards that are mounted in specific connectors or buses. The most common ones are PCI and PCI-E. The first form factor is gradually becoming obsolete and giving way to PCI-E. But such cards can still be found on the market. PCI-E can have different lengths. But when specifying characteristics, this parameter is usually discarded, since it is standardized.
PCI and PCI-E are easy to distinguish
It is worth mentioning separately the PCMCIA standard. This specification was developed as an expansion module and was very widely used in laptops of the past. With its help it was possible to connect not only network cards, but also many types of other equipment. Today this standard is practically not supported.
External USB network cards
A relatively new trend in the adapter market. Represents external device, connection to a USB port. Externally it looks like a flash drive. All microcircuits are hidden in a neat case. In the very simple case may have one RJ-45 connector. A very convenient and compact type of network card.
What does a network card look like and where is it located in a computer?
Finding a built-in network card in a computer is not so difficult. The board that has an RJ-45 connector, a standard connector for almost all Internet providers, will be a network one. In addition, many devices are equipped LED indicators work.
How to find out the network card of a computer if it is integrated? It also has an RJ-45 connector on the back of the system unit, however, the chip itself can be soldered anywhere on the motherboard. To find it, you will have to refer to the schematic map, which usually comes with the motherboard.
What is a network card in a laptop? In most cases, this is a separate Wi-Fi chip and a separate Ethernet. If the first one stands out noticeably, then the second one may be a very tiny chip somewhere on the back of the motherboard.
How to configure a computer's network card
You need to configure the adapter based on your needs. So, in most cases, once installed and connected, it should work out of the box. Quite often you have to change the settings for obtaining an IP address. There are two types: receiving an address automatically and manually specifying it. In most cases, the automatic option is sufficient. You can check which mode is installed or change it by going to the Control Panel of the Start menu.
Here you need to find “Network and Sharing Center” shared access" and click on the link "Connect via local network».
Current connection status window
A status window will appear in which we are interested in the “Properties” button. In the new window that opens, select “Internet Protocol Version 4” and click on the “Properties” button again.
Among the protocols you need TCP/IP version 4 or 6
The next window will prompt you to select the option of obtaining an IP address by setting the switch to the desired mode.
In most cases, the IP address is assigned automatically, so there is hardly any need to configure it
In a special publication we will talk about Wi-Fi routers. You will find out which router Wifi is better, their specifications, how to connect yourself and check out the prices.
What to do if the computer does not see the network card
Quite a common problem. It can be solved different ways, depending on the situation. Let's consider solutions for integrated and internal maps. A situation where the computer does not see the card can arise for several reasons:
- the device is disabled in the BIOS;
- drivers are not installed;
- physical malfunction.
In all other situations, the card should appear in the device manager at least as an unidentified device, which will allow you to install drivers. The Onboard H/W LAN item is responsible for disabling the network card in the BIOS. It must be in Enabled mode. Interestingly, here in the BIOS, sometimes it helps to detect a card by disabling the Green LAN item. This is not a universal approach, since different models On motherboards, these items may be completely absent.
Standard for most mother cards BIOS
As such, the lack of drivers will usually still allow the network adapter to be detected in Device Manager. If the card is built-in, then for detection you will need to install the motherboard drivers. On laptops this is very easy to do by finding required package drivers by device model, then for stationary systems you will have to accurately determine the motherboard model and download drivers from the official website.
ATTENTION!
Always download drivers only from official developer sites. This will allow you to avoid viruses and malware from entering your system and use the most recent version of the software.
As for the physical malfunction, nothing can be done about it. Especially if the card is built-in. All that remains is to buy a new external or internal one.
How to choose a network card for your computer
Basically, the choice of cards for a computer comes from a range of PCI models. You can, of course, look towards USB, but why occupy an external connector in a stationary device if you can carefully install the board inside? PCI may also be different. Specifically, PCI is an earlier connection format various devices. PCI-E is now more common. Its main difference is higher throughput. Therefore, before purchasing, it is advisable to find out exactly what connectors are available on the motherboard, and based on this, choose network device. By the way, most network cards have a PCI-E x1 connector, that is, with one line.
On the market network equipment The brand is no less important. Nowadays, it’s probably only lazy people who don’t produce network adapters. Among the assortment you can find: famous brands, and semi-basement Chinese nonames. Naturally, the quality and reliability of operation will be higher for reputable and expensive cards. But you can find a middle ground by choosing an inexpensive, perhaps Chinese, but factory-made copy. We will review popular manufacturing companies a little later.
As for speed, the average user is unlikely to feel the difference between Gigabit and 100 Mbits per second. Unless he plans to transmit large files a lot on the local network. With the current technologies of Internet providers, it is hardly possible to buy a network adapter with a speed above 100 megabits optimal solution. Network cards for a computer with Wi-Fi are more sensitive to parameters such as speed, ability to operate in multiple frequencies, and supported protocols.
How to choose a network card for a laptop
The era of cards with a PCMCIA connector is over. It is very difficult to find such devices on the market now. Therefore, the solution for laptops is network cards with USB connector. The only noticeable difference between them is the version of the USB interface. Here the higher the better. But do not forget that the port on the laptop must be the same version for full compatibility and to unlock the full potential of the device.
How to install a network card on a computer
Install USB adapter It’s very simple to connect to your computer – just plug it in and you’re done. Therefore, we will consider the installation option internal adapter. Before connecting the network card to the computer, you need to remove the plug on the back of the system unit opposite the corresponding PCI or PCI-E connector. Then you just need to carefully insert the device into the slot and tighten the mounting plate with a screw. All. Naturally, the entire operation must be carried out with the computer turned off.
Manufacturers of popular cards and their products
When you mention network cards, several manufacturers come to mind, whose names are always well-known: Intel, Tp-Link, D-Link, HP, gembird and others. Since network cards do not have any special advanced functionality, let’s take a quick look at the manufacturers and look at their devices.

Network card for computer- This is part of the PC hardware configuration. This device allows you to connect Personal Computer or laptop to networks of any scale and ensure interaction with them. Network card for computer, Usually called an Ethernet card, it also has an alternative name - network interface cards (NIC), network adapter or LAN adapter.
Standard Components
Network card for computer At first it was one of the components of an add-on, which can be purchased and installed on a computer not immediately with all the components, but after some time when the need arises. But today it has become obvious that network card for computer becomes one of the standard components that are installed in the absolute number of all produced desktop computers, laptops and NET-books. Network cards are integrated into big number modern motherboards and other devices are still in the initial manufacturing process. If network card for computer was installed in the system when assembling the system unit, then when connected to the local network it will reveal itself with small flickering indicators located near the network connector on the rear wall of the system unit.
Network Card Identification
Absolutely every one network card for computer must be unique and for all this it is routinely equipped with a so-called “media access control” address, or otherwise known as a MAC, which helps identify each computer transmitting data packets through the network. This address is a 48-bit digital-character sequence that is set by the firmware method, in permanent memory chip (ROM) soldered on the network board. The first row is the 24 bits of the MAC address and is called the group unique identifier “organizationally unique identifier” or OUI. Typically the MAC address is tied to the manufacturer of the network card. Subsequently, it can be replaced with another using MAC spoofing technology.
OSI model
The network card operates mutually at two levels of the open systems interaction model or another OSI. The first level, as a rule, is the physical level, which quite naturally determines the fact that network card for computer can provide physical access to the network. A network card for a computer can also work on a second OSI level model, which is called link layer and who is responsible for addressing. The main task of addressing using these two layers is to encode the MAC address into the data packets sent by each network card on any computer.
Types of network cards
Today, network cards can connect their computers both via cable (physical) connection and via wireless interface. When connecting via cable, a standard network port with RJ-45 connector. Wireless connection connection to the network does not require the use of any physical ports or interfaces.
Characteristics and capabilities of network cards
Both types of network cards, wired and wireless, currently allow approximately the same data transfer speed. It typically ranges from 10 megabits per second to 1000 megabits per second (Mbps), depending on the manufacturer and model. Also, network card for computer serves to connect to the Internet, again via network protocols. , You can find out by following the link.

Many people working for computer or laptop, they don’t even know what a network card is needed on a computer for. How important is it for normal operation operating system. And if there is no need to connect to the Internet or perform tasks to create a local network, you may not think for a long time about what important role it can play Ethernet network card. But there comes a time when problems begin to connect to the Internet using a cable. Or there is a need to connect another computer to the Internet or local network - you have to go to the store and choose an additional network card for the computer.
Why do you need an Ethernet network card in a computer?
The Ethernet network card capability allows you to connect just one network device to organize additional connection, you need to purchase another such board, you should always remember this.
You need to know that the network card is also designed for exchanging information over twisted pair cable (Ethernet). This is a more conventional protocol cable. And the board provides a high-speed coaxial connection via the 1394 protocol, and also organizes Bluetooth or Wi-Fi wireless networks. Therefore, in order to properly organize the necessary network structure, you need to take seriously the characteristics of the card itself. The characteristics of the new device must correspond to the tasks assigned to it in the current period.
It is possible to provide access to documents, printers, shared folders or organize your home network differently. This is done using a network card already built into the motherboard. When routers and routers are used, as is usually the case in practice, one network card will do the job. However, the process of creating a network will be quite complex. Using one device you will have to connect the Internet and your home network. For normal operation of the network with such a connection, you will need to additionally invite a specialist in this field. Although the need to organize such complex networks does not arise very often.
Only one network card built into the motherboard can connect and provide communication between two computers on a home network. To connect to the Internet, you will need to have two network cards, one of which is responsible only for connecting to the Internet. Organizing a connection of two computers in this way in a small company or office is more convenient, simple and profitable. You don't have to purchase and configure a router. The advantage of a network card over a router is its small size. In addition, to set up a router you need to have certain skills and abilities. And another positive quality of a network card is that the connection additional device reduces the reliability of the entire system.
The disadvantage of this scheme is that the main computer with two cards must be constantly turned on, since the Internet will go through it. The router, even in always-on mode, will consume much less electricity, and there is no noise from it. But there are situations when a second network card is simply necessary, for example, in one cafe I worked with, a cash register was connected to the computer via one network card, transmitting its readings to the accounting program, and a router with a local network was connected to the other.
Discrete network card or built-in?
Sometimes it becomes necessary to install an additional network card, even if you have a working one built into the motherboard. Why? I have repeatedly said that devices that are made to perform one task are much better than combined ones. Therefore, a discrete one, that is, a separate one, is usually more reliable and stable in operation than the built-in network card, which is installed by default on the motherboard. Good manufacturer puts all the emphasis on the quality of the card, which means that there will be no savings on its components, for example, the chipset. Also, discrete network cards have a number of other additional features, for example, lightning protection - there are often examples when, during a thunderstorm, the network card built into the motherboard burned out in a working computer.
Which network card to choose for a Windows computer?
Before you go to the store, you need to ask yourself a few questions that will guide you which product to look for:
For computer
For desktop computer experts advise choosing a card compatible with the PCI bus, which consistently exchanges data via twisted pair. At the same time, you need to know that the PCI bus is more common, and it is combined with IBM technology. If the computer device is made according to a different scheme, it may be a MAC, you need to choose a network card that can operate over twisted pair cable. When purchasing such a card, you need to become familiar with the connection options. It may happen that, having purchased a network card, it will be impossible to connect it, because some buses are not compatible with each other, either electrically or in software.
For laptop
The network card for a laptop looks a little different in appearance due to the features of the portable connectors on the laptop's motherboard. It will be more difficult for a beginner to buy it and change it, so the best option- take it to a service center, where specialists will do this, or connect a USB adapter (in the picture below there are 2 network cards for the laptop - cable and wireless).
Wireless network adapter
Organization wireless network will require USB selection or PCI devices Wi-Fi technology. And even in this case, there is no need to buy and connect a router. The choice of network card should mainly be influenced by the connection speed and how it is connected. IN in this case A PCI device is more convenient; there must be free PCI slots. If they are absent, preference should be given to choosing a USB card. And it is important to consider compatibility with the protocol of these boards. In addition, they must be able to connect with each other.
Network cards designed for high speed connection via the IEEE 1394 protocol. Although they were originally created for tree-like connections of various devices. These are devices such as DV cameras, external network drives And so on. However, when using them, it is possible to organize very productive and sufficiently fast connections between computers. A big obstacle to the use of such network cards is their high cost. These boards are much more expensive when compared to the prices of Ethernet boards designed for exchanging information over twisted pair cables.
Manufacturers of network cards
Today in stores you can see network cards from many manufacturers: Realtek, ASUS, Acorp, D-Link, Compex, ZyXEL, Intel, TP-LINK and so on. But you need to take into account that each company makes products for a specific target audience. For ordinary users On the Internet, the most popular cards are Acorp and D-Link - they are inexpensive and at the same time very high quality. The likes of Intel and TP-Link focus on making fairly powerful and expensive products for organizations to install on servers.
Additional technologies that improve performance and convenience that can be implemented in network cards:
- BootRom - allows you to turn on your PC over a local network via remote computer.
- PCI BUS-Mastering - to optimize the operation of the network card, which relieves the load from the main processor of the computer.
- Wake-on-LAN - allows you to turn on your computer using a local network. For it to work properly, the computer must have a motherboard that supports this technology, and the computer must be connected to the network using special cable, if there is no PCI 2.2 support.
- TCP Checksum Offload - also allows the network card to save the processor from unnecessary work. A network card with TCP Checksum Offload support independently processes service information that arrives along with the main data over the network, freeing the processor from this work.
- Interrupt Moderation - reduces the number of requests to the processor. This function will be especially useful in gigabit network cards, which carry a greater flow of information than conventional ones.
- Jumbo Frame - allows you to speed up receiving data from large packets three times faster.
What network card is installed on a Windows 7 computer?
Before purchasing a new one, it would be a good idea to find out which network card is installed in your this moment in computer. This will also be useful if you need to update drivers for it after installation on your computer.
This is very easy to do - I’m showing on Windows 7. So, we follow the path “Start > Control Panel > System”. Here, in the left menu, select “Hardware and Sound” and click on “Device Manager” in the “Devices and Printers” section
By clicking on the plus sign next to the “Network adapters” line, we open the list of boards installed on the computer.
As you can see, finding out which network card is currently installed on the computer is not difficult. But it also happens that the system does not see the network card. This time, a third-party program can help, such as AIDA, which will scan all devices and identify them.
That's all for today, I hope you have decided which discrete or built-in network card is right for you, how to recognize it and which one is better to purchase. I'm sure you will right choice!
Description of network cards for computers and laptops.
Navigation
A network card is a device that allows users to access the Internet, as well as a local network from a computer or laptop. As a rule, modern network adapters have an Ethernet connector to which an Internet cable is connected. This could be a fiber optic cable coming from Wi-Fi devices or the corresponding modem.
In addition, there are also wireless network adapters if the user does not have the ability or desire to run cables across the entire apartment.
In today's review we will discuss in more detail what network cards are, what they are needed for and how they work.
Network cards
As already noted, network cards are essential integral part computer or laptop that allows us to work on the Internet. Network cards may differ from each other in bandwidth, type and other parameters.
What types of network cards are there?
Here we list the main types of network cards:
- Wireless cards are cards that provide an Internet connection when Wi-Fi assistance or Bluetooth devices.
- External - usually used for external connection to laptops via USB port
- Integrated - the most common cards that are built into computers and laptops by default.
- Internal are network cards that can be additionally connected to computers in the corresponding slots on the motherboard.
How do network cards work?
We will not delve too deeply into the operating principle of network cards, since this information will be more understandable only to specialists. Let's explain it more simply. Let's say if you installed fiber optics at home and paid for the Internet, then your provider gives you access to the World Wide Web.
Digital information is transmitted through the fiber optic cable, which is then processed by the network card. There is nothing complicated about it. When you buy a computer or laptop, as a rule, these devices should already have a built-in network card on the motherboard. The driver for it comes along with the drivers for the motherboard. You only need to install the drivers from the disk, which must be given to you by the seller of your computer/laptop.
All this is so simple that most users simply do not realize that there is a network card on their computer. They connect the cable to the network unit of the PC or laptop, pay for the services of their provider and freely use the Internet.
As you might already guess, the computer’s network card is located in its system unit. You just need to open its side cover and pay attention to the lower left corner. You can see this in the screenshot:
How to find a network card on a computer?
If you want to buy a separate internal network card, then you can build it into the corresponding slot in the lower left area of the system unit.
The network card looks like this:
How to find a network card on a computer?

How much does a network card cost?
It's hard to say how much a network card will cost tomorrow, since prices digital devices can constantly change. Different network cards have different prices, let's present some list for today:
How much does a network card cost?
How to choose the right network cards for laptops and computers?
When purchasing a card, of course, you should pay attention to parameters such as media type, bandwidth, and type of network card. It is important to know the classification. But, if you are not an expert, this information you can find out from the seller (buy digital technology only in famous official stores). The most important thing is to know in advance which network card from which company you should look for.
Let's list what you need to know when choosing a network card:
- The most famous top manufacturers of network cards: “ D-Link», « Tp-link», « Gembird», « Acorp».
- The network card must have connectors or a connector to be able to connect to a local network (be sure to ask the seller about this).
- To connect to computers, the network card must have a connector " PCI"(especially if you have old computer), and for computers – the “ PCMCIA».
- It is also important to consider what maximum speed Your network card will be able to provide Internet access. Standard cards support speeds up to 100 Mb per second.
