I have two computers, and the two computers are connected by network cables.

It's good to build an online neighbor.

Steps: Open "Online Neighbors", click "Set up home or small office network", click "Next", click "Next", select "Other", click "Next", select "This machine connects to the Internet directly or through a network hub", click "Next", set your computer name (each station cannot have the same name), set the team name (each station must be the same in order to be in a workgroup and can only be accessed by each other), select "Enable file and print sharing", A dialog box pops up asking if you want to share, click "Yes", click Next, wait for the setup to complete, select "Finish this wizard, I don't want to run this wizard on other computers", click Next, click "Done". Ok, you're good to go after you restart the machine.

Finally, you need to set up sharing for the disks, folders, and files you want to share on your machine so that other machines can see and share those files. Open my computer, find the disk, file or folder you want to share, right-click, click Share & Security, click Share, click Share this folder on the Internet, click Apply, click OK. ok。

Note: You need to do this on every machine in your LAN to share files and printers.

If you have a firewall installed on your machine, you should also adjust its protection level to a low level, or whitelist the IP addresses of machines on the same network. Otherwise, the firewall will block access between the machines.

First of all, there must be a crossover network cable, which is directly connected.

Then set the IP, one set and the other set.

You can see each other in your online neighbors.

Share the file you want to send and copy it.

First of all, you need to have a crossover network cable instead of a normal network cable, if you only have a normal network cable, then you also need a switch.

With any of the above conditions, configure the IP address in the network attributes of the two computers in the same network segment, such as and, and then open the shared directory, enter the IP address of the other computer in the IE window of the other computer, it should be accessible, such as the user name, password, enter the boot user name and password of the computer.

You'll have to buy a router.

Most directly on the Internet, such as QQ, email can be.

If there is a switch or hub. After connecting together, you can use the software "Flying Pigeon Biography". This software is small and fast to send. Generally, it can reach 10m s.

You need a peering network cable, set the IP addresses of two computers, one is, the other is, and then open the sharing.

Open the share, know the other party's IP address, and hit the other party's IP in the start-run process.

Spread with QQ... Pour it with a USB flash drive. If you are not afraid of trouble, you can also spend 2 yuan to buy a network cable that is directly connected.
