One of the simplest ways to connect two computers together is with the use of ethernet cable. For this networking method to work, you need to have a network card installed on both the computers. These networking cards are placed in the PCI slots of the computer. The network card provides an ethernet port to the computer, which provides a facility to connect it with other computers.
So to connect two computers together using an ethernet cable, make sure that both computers have a networking card and if they do not, then buy them and get them installed. Choose a network card which provides high data transfer rate. Buy an ethernet cable. Plug one end of that cable into the ethernet port of the first computer and plug the other end into the ethernet port of another computer. Make sure that you connect the ethernet cable properly into the ethernet port and hear it clicking into place on both sides.
Next, you must switch on the two computers and go to the network settings. I am assuming that you have a windows operating system installed. In case you have any other operating system, run its equivalent network set up utility program. Create a network using the 'set up advanced network' option by logging in as the administrator. Make sure that you don't forget to specify that you are creating this network without a router and directly connecting computers. Name the computer you have logged in as the 'host' while the other computer as the 'guest' and do the same on the other one.
If you are asked to create a network set up disk then create one and run it on the other computer to transfer the network settings. Turn file sharing 'on', when given a choice. Click on properties of drives or folders and enable sharing on network. That should do the trick and enable your two-computer network. Read more on home computer networking tips.
How to Connect Two Computers Together With USB Cable?
You can connect two computers together by another method, which is by using a USB cable. Here is what you need to do. First you need to install the driver software for the USB cable. Insert the installation CD in the drive of one computer and finish the driver installation. Choose 'Link Mode' in the installation process which enables you to transfer files between the two computers. If you choose the 'network mode', it will connect the computer on a network. Repeat the procedure of driver installation on the second PC. Then connect each end of the USB cable to the USB ports of each computer. With that done, your computers are linked for data transfer.
