-A '''bitstring''' is a sequence of [[bit]]s. Anything on a [[discrete computer]] can be represented by a bitstring. In particular, any discrete computer can be encoded in a bitstring, usually called a [[software program]]. Many mathematical structures can also be represented by bitstrings.
-While every conceivable type of data in today's [[computer memory|memory device]]s is indeed stored as a sequence of ONs and OFFs or zeros and ones is indeed a [[String (computer science)|string]] of bits, (ex. '7'<sub>10</sub> == '0111'<sub>2</sub>) bitstrings in the strict sense are used when grouping and packing [[boolean]] [[Flag (computing)|flag]]s in a memory-efficient way. The state of one flag can be set or read using a [[bit mask]].
