The alpha channel is home to the mask: Photoshop: Channels and Masks

An alpha channel contains a mask. Masks and selection outlines are the same things expressed in different ways. Photoshop sees a mask every time you make a selection. So, an alpha channel lets you store a selection for later use and it lets you elaborate on that selection, even using the selection tools themselves.
