Which of the following is not a positional number system?*

The number system having just these two digits – 0 and 1 – is called?A) Decimal Number SystemB) Binary Number SystemC) Octal Number SystemD) Hexadecimal Number System

(A B C D E F) ARE FOUND IN WHICH TYPE OF NUMBER SYSTEM

The number system that uses base-2 is called binary number system while the number system that uses base-8 is called octal number system.In binary system (or base-2 number system,) a total of 2 digits (0 and 1) are used to represent a number of any size (magnitude), whereas in octal system (or base-8 number system,) a total of 8 digits (0, 1, 2, 3, 4, 5, 6 and 7) are used to represent a number of any size (magnitude).The largest digit in octal system is (7)8. Number (7)8 in binary is represented as (111)2. In binary system, three binary digits (bits) are being used to represent the highest octal digit.While converting an octal number to a binary number, three bits are used to represent each octal digit.The following table shows the conversion of each octal digit into its corresponding binary digits.Octal 0 1 2 3 4 5 6 7Binary 000 001 010 011 100 101 110 111For example, an octal number 0246 is converted to its corresponding binary form asOctal Number -> 2 4 6Binary Number -> 010 100 110Hence, 0246 is (010100110)2.Click on Live Demo to understand the conversion of octal number to its corresponding binary number.Similarly, while converting a binary number into its octal form, the binary number is divided into groups of 3 digits each, starting from the exterme right side of the given number . Each of the three binary digits are replaced with their corresponding octal digits.If the group of binary digits to the extreme left side of the number do not have three digits, the required number of zeros are added as a prefix to get three binary digits.For example, let us try and convert a binary number 1101100 into its corresponding octal number.Binary Number -> 1 101 100Binary Number -> 001 101 100 // After prefixing zeros on the extreme left side of the groupOctal Number -> 1 5 4Hence, the octal equivalent of the given binary 1101100 is 0154Click on Live Demo to understand the conversion of a binary number to its corresponding octal form.Select all the correct statements from the given statements.(369)8 is an octal number.Each octal digit is represented using three bits.Binary number (10101010)2 is equivalent to the octal number (252)8.An octal number (364)8 is equivalent to the binary number (011110100)2.
