bit can be processed for the extension of the algorithm 8, to Byte unit for treatment. With 8 bit, it is 2 ^ 8 options. This will significantly reduce travel time significantly, significantly faster speed, but it also has its drawbacks, namely, taking up too much resources. Therefore, considering the speed and resources 2:00, semi-byte look-up table method. Byte is a semi-processed as a unit. As a four bit, it is 2 ^ 4 choice.
