Digital Number System
A digital System can understand position number system only where there are only a new symbols called digits are these symbols represent different values depending on the position.
They occupy in the used in any mathematical or numerical representations to express the presence of the numbers, it is also used to notify certain numerical values to represent and demonstrate. There is number of system which that was has its own binary number system (0,1) octal number system (0,1,2,3,4,5,6,7) decimal number system (0,1,2,3,4,5,6,7,8,9) and hexadecimal number system (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F). Here we was see these in a number can be determined using.
- The digits
- The position of the digit in the number
- The base of the number system
Binary Number system
It is number system which base or radix is only 2 as it name implies it supports only two number 0 and 1. Any values in this number system is represented like this (1001)2. Here base (2) hours that it is a binary number system.

Octal Number System
This very number system uses eight digits 0,1,2,3,45,6 and 7. It also called base eight number system. Each position in an octal number represented a power of the base 8 for e.g.8 last positions in an octal number represent an x power of the base 8 for e.g.8. where x represents the last position.

Decimal Number System
The number system that we use in our day lije is the decimal number system. Decimal number system has base 10 as it used to digits from 0 to 9. In decimal number syste the successive positions to the lept to the decimal point represent units, tens, hundred, thousands and so on. Each position represents a specific power of the vase 10. For example, the decimal number, the decimal number system (1234) consists of the digit 4 in the unit's position, 3 in the's position and its value can be written as:
Hexadecimal Number System
Hexadecimal number system is a number system which has base 16 ranging from 0 to 9 and up to from A to F. means if write completely than it will be like , this 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. A number of hexadecimal number system is written like this (4A7)16 or 4A7(her) hexadecimal number is represented always in 4 bit each.
Alphanumeric Codes
A binary digit or bit can represented only two symbols as it has only two states 0 or 1. But this is not enough for communication between two computers because there we need many more symbols for number from 0 to 9. Punctuation marks and other symbols.
