render target
The image a GPU draws its output into — which need not be the screen itself.
A render target is the destination image that a pipeline writes pixels to. It's often the screen, but can also be an off-screen texture used later, and 'multiple render targets' means a single shader pass writes several outputs at once (say color plus surface normals). These intermediate images are the raw material for effects like post-processing.
