In computers we normally use four different numbering systems - Decimal, Binary, Octal and Hexadecimal.The decimal system is a number system which is used in our day-to-day transactions like currency,counting etc. In this system,the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are used to denote various numbers.In Binary number system, 0's (zeros) and 1's (ones) are the only symbols that are used to represent numbers of all magnitudes (sizes). For example, a normal decimal number 3 (three) is represented in a binary as 11. We shall learn more about it in the later sections.Binary system is mostly used in computers and other computing devices.A number in a particular base is written as (Number)base of number. For example (34)10 is a decimal number (Thirty Four) and (11)2 is a binary number 11 (it is read as One One and not as Eleven) which actually represents a decimal number whose value is 3.Since the decimal number system is more commonly used,the decimal number (124)10 is simply written as 124. However, if the same number has to be represented in binary system, it is written as (1111100)2.Similarly, the octal number system uses 8 as its base. It is generally used in digital displays and in representing file permissions under UNIX/Linux operating systems.Hexadecimal system or Hex is a number system that uses 16 as the base to represent numbers. We shall learn more about octal and hexadecimal number systems in the later sections.Select the correct statements from the given statements.A number system that uses only two digits, 0 and 1 is called Binary number system.The ten digits used in the decimal number system are from 1 to 10.The two symbols 0 and 1 are known as bits in a binary system.The base of an octal system is 8.Close
