How to connect three systems?

Hello,

I would like to get some help regarding the connection of three computers. I want to connect three computers using a hub. I have a netgear hub. And have three straight cables. I just want to know how to connect them.
And one more thing, I dont want to use it for internet connection. I just want to know how to connect them without internet. I would be thankful if somebody helps me out in this issue.

Thanks a lot in advance.
