The parallel major keeps the same root note but raises the third, giving the same key a brighter, happier sound.
The dominant is a fifth above the root, and it builds tension that pulls strongly back to this chord.
The subdominant is a fourth above the root (a fifth below), and it usually leads on to the dominant or back home.
