a wishbone is normally the triangle and a ball joint mounted to the stub axle.
4 link is dynamically the same only each arm of the wishbone is separate and mounted to the stub on a shaft rather than ball joint.
Many will use wishbone to cover all as the DYNAMICS of the setup are the same. But nit-picking () the wishbone is only if it is a single unit. The rest are multi-link arms.
Wishbones or "parallel arms" can be used in top , bottom or both of the stub axle to body.
