How to Connect Computers Together to Act as One System

1. Plug all the computers you intend to link together into an available power outlet or power bar. Place the computers near one another.
2. Place your networking adapter near the computers and plug it in as well. You can purchase these adapters at most computer supply stores.
3. Plug one end of a crossover Ethernet cable into the Ethernet port on one of the computers you intend to link. Plug the other end of the crossover cable into the Ethernet port at the back of the adapter. Repeat the process with the remaining computers. There are multiple Ethernet ports on the back of the network adapter.
4. Connect the cable of one computer monitor to the monitor cable jack on the back of the adapter.
5. Plug the end of a keyboard cable into the keyboard cable jack on the back of the adapter.
6. Turn on all computers and the monitor. You can now view all computers on the single monitor and control them via the single keyboard.
