A single square within the matrix is called a ______.

Explanation:
Pixels are the smallest addressable units in a digital image. A single square in the two‑dimensional image matrix represents one pixel, which holds its color or intensity value. A voxel belongs to three‑dimensional data, so it isn’t used for flat images. A cell is a generic term for a grid entry, but in imaging the precise term is pixel, and a dot isn’t the formal unit used. Thus, the correct term is pixel.
