In computer science, a mask or bitmask 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 or off, or inverted from on to off (or vice versa) in a single bitwise operation. An additional use of masking involves predication in vector processing, where the bitmask is used to select which element operations in the vector are to be executed (mask bit is enabled) and which are not (mask bit is …

In other words, no 1 bits overlap between a power of 2 and a power of 2 minus 1. This isn't true of other non-powers of 2. For example, 1001 minus 1 is 1000, which shares a 1 bit.
