Question

The maximum number of bits sufficient to represent an octal number in the binary format is :

• A. 4
• B. 3
• C. 7
• D. 8

Answer 1

Answer:

B. 3

• The octal number system comprises of only 8 digits and uses the digits 0 to 7. That means there are only 8 symbols or digits (0, 1, 2, 3, 4, 5, 6, 7) used to form other numbers. • Binary numbers are made up of only 0's and 1's. A binary number is represented with a base-2. A bit is a single binary digit. • Decimal number system is also known as the base 10 positional numeral system as this type of number system has the base number as 10 and uses digits from 0 to 9. • The hexadecimal system contains 16 sequential numbers as base units, including 0. The first nine numbers (0 to 9) are the same ones commonly used in the decimal system. The next six two-digit numbers (10 to 15) are represented by the letters A through F.
