Binary Number
[edit | edit source]Binary numbers are numbers in base two which consists of two digit 0 and 1 . A series of 0's and 1's can be formed to represent info
For example number from 0 to 9 can be expressed as binary numbers of four bit as shown
| 1 | 0001 |
| 2 | 0010 |
| 3 | 0011 |
| 4 | 0100 |
| 5 | 0101 |
| 6 | 0110 |
| 7 | 0111 |
| 8 | 1000 |
| 9 | 1001 |
Binary Coding
[edit | edit source]Since in binary number system there are only two digits 0 and 1 called a Bit . So 1-bit binary number refers to number of 1 digit either 0 or 1 . 2-bit binary number refers to number of 2 digit namely 00, 01, 10, 11 and there are 4 of such numbers which equivalent to 22. Hence, there are 2n binary numbers of n bits
The process of using binary numbers to represent info is called Binary Coding
For example with 1-bit binary number 0 and 1 can be used to represent number 0 and 1 in our system .
With 2-bit binary number can be used to represent number 0 to 3 in our system as follow
- 00 represents 0
- 01 represents 1
- 10 represents 2
- 11 represents 3
With digit 0 and 1 we have three bit binary numbers of 000, 001, 010, 011, 100, 101, 110, 111 which equivalent to 0, 1, 2, 3, 4, 5, 6, 7
