question 9 of 25
an octal number system uses which set of symbols to represent data?

a. 0,1
b. 0,1,2,3,4,5,6,7,8,9
c. 0,1,2,3,4,5,6,7
d. 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f

Explanation:

The octal number system is a base - 8 number system. In a base - n number system, the symbols used to represent data range from 0 to n - 1. For base 8, the symbols should be from 0 to 8 - 1=7. So the octal number system uses the symbols 0, 1, 2, 3, 4, 5, 6, 7. Option A is for binary (base 2), option B is for decimal (base 10), and option D is for hexadecimal (base 16).

Answer:

C. 0, 1, 2, 3, 4, 5, 6, 7
