A bitvector is a string of bits.

With a logical function, LogicalOr, LogicalAnd, etc,
each bit of a bitvector can be changed.

Thus each bit of the bitvector is a value on its own, representing the state of a specific object. The bitvector can identify the state of a range of objects since the individual bit can be changed with a bitwise operation such as  -> BitWiseOr . 

Most likely a bitvector will have a typical length. 8-bits, 16-bits, corresponding to  -> BitGroups . 


For instance if we have a range of devices connected to our computer, each connection could be represented by a bit to indicate if we have access to the device or not.

0 is open 1 is closed. If we have a range of 8 devices our bit-vector would be:

| 00000000 |

If device zero would be a printer, located in the bitstring at
the first position from the right, that is not available bit-0 would indicate closed with a ' 1 ' :

| 00000001 |

If the printer would become available the system would update the bit-vector
with a BitWiseAnd operation:

| 00000001 |
| 00000000 |
 ----------
| 00000000 |

and bit-0 becomes a ' 0 ', since 1 AND 0 => 0 .


Otherwise if the monitor at bit 6 becomes disconnected, the system would update the bitvector with a  -> BitWiseOr : 

| 00000000 |
| 00100000 |
 ----------
| 00100000 |

since since 0 OR 1 => 1 .
