In computer science, a mask is data that is used for bitwise operations, particularly in a bit field.
Using a mask, multiple bits in a byte, nibble, word (etc.) can be set either on, off or inverted from on to off (or vice versa) in a single bitwise operation.
Famous quotes containing the word mask:
“The Liberal State is a mask behind which there is no face; it is a scaffolding behind which there is no building.”
—Benito Mussolini (1883–1945)
