Every computer owner will definitely one day start looking for an answer to the question of how to set up a local area network between two computers. This way of connecting multiple computing systems is still incredibly in demand, despite its venerable age (it turns 47 this year).
This is not surprising, given the extremely low cost of network deployment, the availability of equipment configuration and quite decent digital information transfer rate by modern standards. In addition, the use of wires as a carrier medium allows for high reliability of data exchange.
Materials and equipment
As you know, a local network of computers allows you to effectively solve the problem of organizing communication between computer systems. You just need to purchase a special cable (usually a twisted pair) with connectors installed at the ends, connect them to the outputsnetwork cards of two computers and, of course, configure. It is desirable that the cards support the same standards. All modern boards already contain built-in network adapters.
Note that when connecting several systems using a switch, hub or router, the network card settings will be different than when a local network is established between two computers. However, the principle is the same, so next we'll look at a simpler option.
How to set up a local network between two computers
So, the cable is bought, and the connectors are connected to the computer connectors. Immediately, we note that the length of the segment should not exceed 100 meters (for 100 megabits). In addition, the problem of direct and reverse crimping of connectors has long been a thing of the past, so this issue can not even be raised (sometimes this feature is remembered for some reason). The next step is to configure the operation of the network card itself. To do this, through the control panel or by selecting "Properties" of the shortcut "Computer", go to the "Device Manager", where in the displayed system list, check the item "Network adapters". Here you should configure exactly the adapter to which the cable is connected.
In the "Advanced" item, you must force the "Speed and Duplex" to the required mode. It has been noted that auto-negotiation may slow down the transmission. Well, since we are considering how to set up a local network between twocomputers, then the same steps should be performed on another computer system.
Correct addresses
The next step is to open the "Network and Sharing Center" (the properties of the monitor icon next to the clock in the system tray) and select "Change adapter settings" from the list on the left. Here you need to call the properties of the network card that was previously configured in the "Device Manager". Further, if the question is how to set up a local network between two computers, then Protocol version 6 can be disabled by unchecking the corresponding entry - it is needed for the Internet, and so far the vast majority of small systems work successfully without it, using a proven fourth time. It remains to make changes in TCP / IP 4: double-click and select "Use the following address." Here you need to register 192.168.0.1, and set the network mask to 255.255.255.0. No further changes are required. On another computer, the IP address will be different - 192.168.0.3. The rest of the settings are identical.
If the network is down
Sometimes you have to set the same working groups. To do this, call the "Computer" properties and proceed to the "Advanced Options". In the window that appears, select the "Computer Name" tab, then "Change", and then write the name of the workgroup there. It is important that it be the same on both computers.
