Connection between two computers cable. How to connect two computers with each other into a single network. P Asshesive Internet for LAN

Sometimes there is a need connect two computers over the networkBut not always there is network equipment. What to do if there is no swirl, router or modem? There is one way out - connect two computers with one cable. Today we will consider two situations: when two computers have on one network card and when two network cards are installed on one of them.

In the first case, you can only configure the network between two computers. In the second case, the network and the Internet will work on two PCs. Let's deal with what you need, so that two computers "shoved":

1. Actually, two working computers with network cards,
2. Cable for direct connection of computers,
3. Smooth hands (2 pcs).

Cable can be bought already in finished form in any store computer equipment, Only it is necessary to clarify that it is needed to connect "Computer" - "Computer" (Cross Cable). If you want, you can enable cable yourself. In detail how to enable cross cable I have already described in the article. In short, the crimping scheme looks like this:

Here is an example of a finished cable:

When all components are ready for you, you can begin to conceive.

Connect two computers with one network card

When buying a computer or system Block In most cases, you can see only one network card (it is built into motherboard). In this case, consider such two computers that have only one network cards. Below you can see the connection scheme:

When the cable is connected in two PCs, configure the network. Right-click on the network icon on the taskbar and select the "Network and Shared Access Center" item.

A window will open, where all network adapters will be visible (I have two of them: one is physical, the second is virtual from VirtualBox). Click the double click on the left mouse button on the physical adapter (connection by local network).

The Network Properties window will open, where we have to choose "Internet protocol version 4 TCP / IPv4" by pressing two times the LKM,

After that, in the TCP / IPv4 Protocol Properties window, specify the parameters of our network. Watch the data as shown below on the screen,

Note, the main gateway must be empty, as well as a preferred and alternative DNS server. After the data is made, click the OK button and once again.

The same settings are done on the second computer, with the exception of the IP address. He should look like this 192.168.0.2,

After all the above manipulations, two computers will work on the same network. To check the performance of the one and the second PC. To do this, open the command line on the first computer (Win + R and drive the "CMD" command) and introduce:
ping 192.168.0.2.
the exchange of packages must be successful as in the screenshot:

Now do the same actions and on the second computer, Ping Ping 192.168.0.1
in command line. If you have received a report on the successful exchange of packages, I congratulate - the network between the two computers is configured. If the ping does not pass, then most likely you have made a mistake somewhere. Check again everything is careful. By the way, access to the computer can be blocked by Windows Firewall or Antivirus, so if the network fails to be configured, then try to disable these two utilities.

We connect two computers, on one of which there are two network adapters

Let's now consider the case when you need to connect two PCs with the possibility of exit global Network (the Internet). As I said above, this option is possible if two network cards will be installed on one computers (in one we connect the second computer cable, in the second - Internet cable).

Good day, dear readers.
If two computers are used near, it is logical to make a connection to local windows networks 7. It is convenient to share files, information, for joint games or using one equipment. This tool provides additional comfort, as there is no need to constantly use the portable memory or exchange data via the Internet, although the speed of the latter today allows you to do it quickly. I will try to tell everything that I know regarding this technology.

So, for a start, it is worth a little talk about what is connected on the local network. It is a link between two and more computers. This is carried out by cable or wireless technology. As mentioned first, the technology is allowed to exchange information, and indeed contributes to the acceleration of the workflow.

Creature( )

We will not stop on what components are necessary for physical communications. Before directing the connection, you must specify a single workgroup on all devices. To do this, make some simple movements:

As mentioned first - the value should be equally on all devices that will be in one bundle. At the same time, the string " Full name»Each equipment is unique.

After you need to go to " Network Management Center" This can be done through " Control Panel"Or find the connection icon in the tray, and then click on it right-click.

increase

In the left side of the window we find the item "". Now we need to turn on everywhere network detection and setting B. automatic mode. In addition, it is necessary to open general access.

increase

Then go to " All networks" Find the last item " Common Access with Password Protection"Where we need to turn it off.
In addition, it is necessary to such computers Enable the ability to detect individual folders.

As a result, catalogs from different users should appear in the network environment.

If this did not happen, we go to the main menu " Network Management Center"And click". Then we do everything according to the prompts.

increase

No icon near the clock( )

Do not immediately worry. It is possible that the corresponding function for some reason was disabled.

So, if you have bad icon near the clock, we do the following:

Network does not work( )

Every user who is already for a long time Interact with other devices in this way, at least once in his life, I met a problem when the connection simply disappears. This can happen for several reasons. The most common are problems with network equipment. In most cases, it helps a simple reboot.

Sometimes it is necessary to re-register all parameters. How to configure switch or router? To solve this issue it is better to turn to a specialist, as it often depends on the specifics of use.

Installing a network printer( )

Separately, it is worth saying about connecting the printer over the network. Believe me when more than one computer is used in the room, sooner or later it will be necessary to print from each of them. Do not move constantly documents from one to another. To do this, do some movements:

How to enable the apparatus we need on other PCs or laptops? Just need to install it. For this:

At first glance, the installation of the network seems to be a complex process. But actually it is not. Of course there are such connections that require special knowledge from a specialist. In fact, if you are not sure about your actions - it is better to turn to the master.

I hope you helped the information I set out above. Subscribe to updates, and you can first recognize the most interesting data regarding windows work and computer technology generally.

Hello, dear readers blog Help beginner computer user. In this article we will look at how connect two computers between themselves network Using twisted pair. Using twisted pair the most acceptable option because this type The conductor has a relatively low price, but provides a sufficiently high data transfer rate and the distance between computers.

To perform this task you must have:

Two network cards (one on the computer). If they are already available (for example, integrated into the motherboard), the better;

Cable twisted para — copper cables based on twisted pairs (that is, two wires twisted with each other and form a pair) Wiring (Twisted Pair), which are divided into shielded (shielded pair, STP) and unshielded (unshieded twisted pair, UTP);

Fig. 1 cable twisted pair

Two plugs RJ-45 (Jack);

Crimping tool ("Crimper").

Fig. 2 Crimper.

First of all, we need to measure the distance between computers (not directly, but by those paths that the cable will be laid). Add to the resulting number several meters and buy (it is easier to choose a twisted pair of unshielded - UTP). Need to remember that distance between computers should not exceed 100 meters. We also buy two RJ-45 plugs and a crimp tool (you can enhance the twisted pair immediately at the point of purchase, but we will go different ways and do everything yourself).

When purchases made needed to clip cable. Since they connect two computers with each other without using additional network equipment (Svish, Hub), we need Cross-Over cable crimping cable (zero-hubnaya). First, it is necessary to prepare the conductors of the twisted pair of crimping: we cut the conductor shell about three centimeters (from both ends), we break the wires and distribute them to colors in one plane with each other, according to the picture.

Fig. 3 The procedure for the location of the conductors when performing crimping: a) the first end of the cable; b) the second.

We take the RJ-45 plug and insert into it in turn prepared conductors of the twisted pair. Do not forget about the distribution of conductors in color. When the conductors entered to the end of the fork, we take the crimper (crimp tool) and crimp (insert our jack at the crimper and squeeze the handles to the end). Made? We repeat the same actions with the reverse end of the twisted pair. Do not forget that here the conductors are distributed over several other colors.

When everything is ready to connect Jackie into the connectors on the network cards of both computers and turn on the computer. We can only set up operating system. In our case, this is Windows XP.

When the computer turned on, configure the working group of our network and give the name to the computer. To do this, you call the "My Computer" folder context menu on the desktop (by clicking the right mouse button on this shortcut and select properties - see Figure).

If there is no "My Computer" label on the desktop, we do everything using the Start button menu. In the window that has opened, go over the "Computer Name" tab. In the "Description" field, you fit the desired, click the "Change" button. We prescribe the name of the computer and the name of the working group (in our case it is "autp" and "domm", respectively) at its discretion.

Press the "OK" button (twice). A window appears asking for a reboot. Choose cancellation. After that, go to the "Control Panel" through the Start button, select "Network Connections". After switching to the "Network Connections" folder, looking for a label "Connection over LAN". Click on the label right-click and call "properties".

On the General tab, in the "Components used by this Connection list:" click on the TCP / IP Internet Protocol.

In the window that opens, put the box next to "use the next IP address".

Greetings all visitors.

Nowadays, many at home have several computers, however, not all of them are combined into a local network ... And the local network gives very interesting things: you can play network games, share files (or use generally disk space), work together on documents, etc.

There are several ways to combine computers in the local network, but one of the cheapest and simple is to use it. network cable (Normal twisted pair), connecting network cards of computers. That's how it is done and consider in this article.

What do you need to start work?

1) 2 computers with network cards, to which we will connect a twisted pair.

Everything modern laptops (Computers), as a rule, have at least one network card in their arsenal. The easiest way to find out if you have on a PC lAN card - It is to use some utility to view the characteristics of the PC (for these utilities, see this article :).

Fig. 1. AIDA: To view network devices, Go to the "Devices / Windows Devices" tab.

By the way, you can also pay attention to all connectors that are on the laptop housing (computer). If there is a network card - you will see the standard RJ45 connector (see Fig. 2).

Fig. 2. RJ45 (standard laptop housing, side view).

2) Network cable (so-called twisted pair).

Most easy option - Just buy such a cable. True, this option will be suitable if the computers are not far from each other and you do not need to drive a cable through the wall.

Fig. 3. Cable with a length of 3 m. (Twisted pair).

With the connection of 2 computers to the network cable: all action in order

(Description will be built on the Windows 10 OS (in principle, in Windows 7, 8 - identical setting). Some terms are simplified or distorted, with the aim of simpler explanation of specific settings)

1) Computer connection with a network cable.

There is nothing cunning here - just connect computers with cable and turn on both. Often, next to the connector, there is a green LED that will signal you that you have connected the computer to some network.

Fig. 4. Connect the cable to the laptop.

2) Setting the computer name and working group.

The next important nuance - in both computers (connected cable) must be:

same working groups ( in my case, this is a workgroup, see fig. five);
different computer names.

To set these settings, go to " MY COMPUTER» ( or this computer), Next, in any place, click the right mouse button and in the pop-up context menu, select the link " Properties". Then you can see the name of your PC and the Working Group, as well as change them ( see green circle in Fig. five).

Fig. 5. Set the computer name.

After changing the name of the computer and its working group - be sure to restart the PC.

3) Setting up a network adapter (set of IP addresses, subnet masks, DNS server)

Then you need to go to the panel windows management, address: .

Actually, then you should see your network adapterif it is connected to another PC cable - it should not burn any red crosses ( see fig. 6, most often, the name of such an Ethernet adapter). You must click on it with the right mouse button and go to its properties, then go to Protocol properties " IP version 4.» ( in these settings you need to go on both PCs).

Fig. 6. Properties of the adapter.

Now on one computer you need to set the following data:

IP address: 192.168.0.1;
Subnet mask: 255.255.255.0 (as in Fig. 7).

Fig. 7. Setting the IP on the "first" computer.

On the second computer you need to set several other parameters:

IP address: 192.168.0.2;
Subnet mask: 255.255.255.0;
Main Gateway: 192.168.0.1;
Preferred DNS server: 192.168.0.1 (as in Fig. 8).

Fig. 8. Setting the IP on the second PC.

Next save the settings. Directly configuring the local connection is complete. Now, if you go to the conductor and click the link "Network" (left) - you should see computers in your working group ( true, while we have not yet opened access to files, this is now now ...).

To AK open access to the folder (or disk) for users of the local network

Probably, this is the most common thing that needs users who need to unite in the local network. It is done quite simple and quickly, consider everything in steps ...

1) Enabling shared files and printers

Come in the Windows Control Panel along the way: Control Panel \\ Network and Internet \\ Network Management Center and Common Access.

Fig. 9. Network and Shared Access Management Center.

Next, you will see several profiles: guest, for all users, private (Fig. 10, 11, 12). Task Simple: Enable everywhere access to files and printers, network detection and remove password protection. Just set the same settings as shown in Fig. below.

Fig. 10. Private (clickable).

Fig. 11. Guestbook (clickable).

Fig. 12. All networks (clickable).

Important moment. You need to make such settings on both computers online!

2) disk / folder

Now just find the desired folder Or the disc to which you want to give access. Then go to its properties and in the "tab" Access»You will find the button" Extended setting", And click it, see fig. 13.

Fig. 13. Access to files.

In the extended setting, check the box opposite item " Open sharing folder"And go to the tab" permissions» ( by default, read-only access will be opened, i.e. All users on the local network can only view the files, but not edit them or delete them. In the "Permissions" tab, you will be able to give them any privileges, right up to complete removal All files ...).

Fig. 14. Allow sharing folder.

Actually, save the settings - and your disk becomes visible to the entire local network. Now you can copy files from it (see Fig. 15).

Fig. 15. Transfer of a file on LAN ...

P Asshesive Internet for LAN

Also a very common task that users encounter. As a rule, one computer is connected to the Internet in the apartment, and the rest get access to it (if, of course, the router is not installed :)).

1) First go to the tab " network connections» ( how to open it is told in the first part of the article. You can also open it if you enter the control panel, and then in the search bar, enter "View network connections").
