At the beginning of the 18th century, levenitz invented the binary number. At that time, he certainly did not expect that the binary will have such a wide application in the information age. The binary number features reliability, simple operation,
The binary uses only the numbers 0 and 1, where each number corresponds to one bit (bits). In general, we will use each 4-bit or 8-bit as a group, which is called half-byte (nibble) and Byte, respectively.We are interested in the binary value
