In mathematics and digital electronics, a binary number is a number expressed in the base-2 digit system or binary digit system, which uses only two symbols: usually "0" (zero) and "1" (one).

Base-2 is a position with a radix of 2 points.
Each digit is referred to as a bit.

Due to its direct implementation in digital electronic circuitry using logic gates, binary systems are used by almost all modern computers and computer-based devices.
Computer number systems are the technique of representing numbers in computer system architecture, which we define as the computer number system (number system).

Types of Number System

Binary Number System: Binary Number System consists of only two digits '0' and '1'. This binary number system is also called the Base 2 Number System because the base number of a binary number system is 2 because it has only two digits.

Octal Number System: The octal number system consists of only eight (8) digits 0 to 7. Each number is represented by 0,1,2,3,4,5,6 and 7 in this number system, its base is 8. The base of the octal number system is 8 because it has only 8 digits.

Decimal Number System: The decimal number system consists of only ten (10) digits from 0 to 9. Each number in this number system represents 0,1,2,3,4,5,6, 7,8 and 9 with Base 10. The base of the decimal number system is 10 because it contains only 10 digits.

Hexadecimal Number System: The hexadecimal number system consists of sixteen (16) alphanumeric values ​​(Alphanumeric Values) 0 to 9 and A to F. Each number represents 0,1,2,3,4,5,6, 7, 9, 9, A, B, C, D, E and F with this number system, its base is 16. The basis of the hexadecimal number system is 16 because it has 16 alphanumeric values. Here A is 10, B is 11, C is 12, D is 13, E is 14 and F is 15.
