Hello i have a question my logitech z906 speakers have connector but its not like you have normally the green what you plug in your green cycle in the motherboard, there are 3 of the connectors and the colors are pink, black and the green so i plugged the green to the pc and it works normally but my ask is why there is 3 ?? i mean like it should have some purpose

Those are 5.1 speakers.
Analog connectors are:
1 connector for front left/right,
1 connector for rear left/right,
1 connector for center/subwoofer.

On 5.1 systems you usually use digital optical connection instead. It's one cable instead of 3.

i dont even have these connector holes in my motherboard

What model motherboard do you have?
It's possible, it doesn't support 5.1 sound. Then you'd need discrete sound card.

Your system supports 5.1 via analog too.
Read user manual (page 21 - ports and connectors)

If you connect only green connector, then only front left/right speakers work.
