wire conecters and display

can some one please help me what are the wire connectors in this picture called and where can I get some I need some so I can hook up my driver boards I have no way to get my machine running till I do and the display in the picture also I blow this one up and would like to get one if any one has a extra one or two because I have a 3/4/5 axis cnc machine I am trying to get going I am on a small budget thank you every one for helping me

I believe they are called "molex" wire to board connectors.

I've called the green connector a Phoenix connector, the white connector in the board is a PCB header of some sort, it is difficult to tell in the photo of it is keyed, different manufacturers use different key layouts. Molex is one brand name, AMP is another, there are other name brands that have slipped from my memory. Digikey should have something that will fit, although you may need a print catalog to find it.

thank you for the info it will help but I am looking for the display really not so much for the converter but the green one is a good start and the display where can I get one for kind of cheap
