When you want to know if a key is present or not in the list, you run it through the hash function and check if the corresponding bits in the bitmap are “1” or “0” If one of the bits is “0”, you know for sure the key is not in the list. If all the bits are “1”, the value may be present.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
