In each computing and digital communications, the bit is that the most elementary unit of information. The word could be a combination of 2 binary digits. A logical state with one amongst 2 potential values is portrayed by the bit.
Main body:
1 bit: 2 strings: 0, 1
2bit: 4 strings: 00, 01, 10, 11
3bit: 8 strings: 000, 001, 010, 011, 100, 101, 110, 111
4bit: 16 strings: 0000,0001,0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001. 1010, 1011, 1100, 1101, 1110, 1111
5bit: 32 strings
6bit: 64 strings
7bit: 128 strings
8bit: 256 strings
9 bits: 512 strings
OR this can be done by
Each bit has 2 possible values, so a string of length 9 has 2⁹ = 512 possible values.
Hence total bit sting are 512.
