Number of owners of two or more home computers (laptops) are constantly increasing. Each of the lucky from time to time it is necessary to transfer certain files from the hard drive of one computer to another's hard drive. For these purposes, you can use removable storage, Bluetooth, etc., but when it comes to transferring large amounts of information, the most practical and quickest way to be a direct connection between two computers through their network cards. In addition, such a compound can be used to connect a second computer to the Internet connection first and address other problems. To connect two computers together should: 1. The presence of hard-working network cards in each of the connected computers. How to check: go to "system properties" (right-click on the icon "My Computer" on your desktop or "Start" menu, and choose "Properties").

Then on the tab "Hardware" click on "Device Manager". In the "Networking" should be displayed network map (called … Ethernet Adapter …, … Network Connection … or something like that). If the network card in the specified section does not appear, or it is disabled in the BIOS, or on the computer it's not at all or it is defective.

2. Appropriate cable (the so-called cross-over). The cable from the DSL-modem will not work, but looks very similar. Its can be made at home, but in this case, except a piece of cable "twisted pair" of desired length and two RJ-45 jacks, which fasten to both its ends, we also need a special crimping tool.
