question 10 of 25
a hexadecimal number system uses which set of symbols to represent data?

a. 0,1,2,3,4,5,6,7,8,9

b. 0,1

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 hexadecimal number system is base - 16. It needs 16 symbols to represent values. The decimal digits 0 - 9 are used for values 0 - 9, and the letters A - F are used for values 10 - 15 (where A = 10, B = 11, C = 12, D = 13, E = 14, F = 15). Option A has only 10 symbols (0 - 9), which is for the decimal system. Option B has 2 symbols (0,1), which is for the binary system. Option C has 8 symbols (0 - 7), which is for the octal system. Option D has 16 symbols (0 - 9 and A - F), which matches the hexadecimal system's symbol set.

Answer:

D. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
