A bit pattern can represent (2^n) symbols, where (n) is the number of bits in the pattern. For example, a 3-bit pattern can represent (2^3 = 8) different symbols, ranging from 000 to 111 in binary. Each additional bit doubles the number of possible symbols that can be represented.
There are 16 decimal numbers that can be represented by 4-bits.

A total of 65,536 items can be represented with 16 bits. A total of 64 items can be represented with 6 bits and 1024 items with 64 bits.

The number of bits needed to represent one symbol depends on the total number of unique symbols. The formula to calculate the number of bits required is ( n = \lceil \log_2(S) \rceil ), where ( S ) is the number of unique symbols. For example, to represent 256 unique symbols, 8 bits are needed, since ( \log_2(256) = 8 ).
