How to connect two computers together with a network cable for data exchange?

The easiest, connected, both computers open QQ, and then use QQ to upload files. Because you are a local area network, the speed is around, don't change the IP address or anything, it's too complicated.

The network cable is connected to the computer network port, a set IP address, a setting, turn off the firewall, set up a file share for XP, win7, you can see.

The practice of crossing the line is: 568A standard at one end and 568B standard at the other end.

568A standard: green-white, green, orange-white, blue, blue-white, orange, brown-white, brown-white.

568b standard: orange white, orange, green white, blue, blue white, green, brown white, brown.

The following first introduces some win7 systems how to set up LAN sharing and transfer files to each other.

1. Turn on the two computers first, then connect them with network cables, and plug them directly into the RJ45 network cable port that you usually use to surf the Internet.

2. Find the file you want to transfer on your computer first, and then set up sharing. Method: Select the disk or folder to be shared, right-click, click Share, and then do the following operations. The operation is as follows:

5.Once you're OK, you'll see that we're connected to both computers and can see the files we shared earlier.

6.You can open the local disk, right-click to copy and paste, and achieve the purpose of our file transfer.

Step 1: Connect the two computers with network cables.

Step 2: Modify the data on both computers separately. Click Control Panel - Network Sharing Center - Local Connections - Properties - Internet Protocol Version 4, and make the following changes in the pop-up dialog window:

The first notebook is modified as follows: Select - use the following IP address, IP address subnet mask The default gateway uses the following DNS server address, preferred DNS server address Alternate DNS server OK - OK - Close.

The second notebook is modified as follows: Select - use the following IP address, IP address subnet mask The default gateway uses the following DNS server address, the preferred DNS server address is the alternate DNS server OK - OK - Close.

Step 3: Both computers make the following changes, the Control Panel - Network Sharing Center --- change the advanced sharing settings - except for the last item "Turn off password protected sharing" - all but enable - save changes.

Step 4: Find the folder you want to share - right-click - share - specific users - click the triangle to select everyone - add - select the folder you want to share - done.

When buying a network cable, tell the merchant that it is a dual-machine direct connection, and he will make the network cable in a different order at both ends. Just use the reconnection to connect the network card of the two machines, and the rest is the same as your router, set up the same workgroup, develop guest users, set up shared folders, and open the online neighbors to see each other. If you can't connect to it, add protocols such as IPX.

Use crossed lines. That is, one end of the RJ45 crystal head uses 568B (white orange, orange, white green, blue, white blue, green, white brown, brown), and the other end uses 568A (white green, green, white orange, blue, white blue, orange, white brown, brown).

Crossover wire for the same kind of equipment.

Straight-through wire for dissimilar equipment.

Therefore, a crossover cable should be used between the two computers, and a straight cable should be used between the computer and the router.

The line sequence is different at both ends of a cross line, while the line sequence is the same at both ends of a straight line. Specifically, the straight line is 568a at both ends, or the cross line is 568b at both ends, 568a at one end and 568b at the other end

Standard 568a: green-white-1, green-2, orange-white-3, blue-4, blue-white-5, orange-6, brown-white-7, brown-8;

Standard 568B: Orange-White-1, Orange-2, Green-White-3, Blue-4, Blue-White-5, Green-6, Brown-White-7, Brown-8.

Two computers.

One network cable. Steps: 1. Connect the two computers directly with network cables.

2. First computer settings 1: Open the settings panel.

4. The second computer also opens the settings.

5. The second computer, then open cmd and ping the first computer. Keyboard "windos key+r" and type cmd and press enter. If there is time to return as shown in the figure on the right, it means that the two computers are successfully connected.

6. Then find the file you want to transfer: for example, the file "test" on drive D.

7. Then click in the order in the picture.

8. The following dialog box appears:

9. Turn on the second computer and enter the address to access.

10. Enter the folder shared by the first computer.

Note: If you want to enter the account password, enter the account password of the computer you want to access, and if the computer you are accessing does not have an account password, you can create one.

Docking between two computers with network cables (twisted pair cables, 1 3 2 6 switching), the specific steps are as follows:

1. Make a [twisted pair], and the end of the crystal head is arranged in the order of white orange, orange, white green, blue, white blue, green, white brown, and brown. The other end is in the order of white-green, green, white-orange, blue, white-blue, orange, white-brown, and brown. Don't make the wrong arrangement!

If you really won't buy one, it's 3 yuan.

The other computer is set as above, but the IP address cannot be the same, you can change to share files between the two computers.

Then you do the root cascade line, the two ends are standard A, the other end is standard B, and then the network card is configured with the same network segment.

For direct connection, a cross line should be used, with 568A at one end and 568B at the other
