in the ocatal number system the base is 8.so in this system there are only eight symbols like digits
0 to 7(one less than base).
again each position in an octal number represent a power of the base(8). thus the octal number 2057 written as (2057)O.
observe that since there are only 8 digits in the
octal number system. so total cube exponent of 2=8
are sufficient to represent to any octal number in binary.
