8 bits = 64 character
A nibble (also known as a nybble or nyble) can represent half a character(two nibbles are needed for a valid ASCII character). A nibble is made up of 4 bits and those 4 bits are usually represented by a single hexadecimal value. 4 bits only allows for 16 combinations, 8 bits allows for 255. An ASCII character is represented by two hexadecimal characters, which is the same as 8 bits or two nibbles.
There are 16 decimal numbers that can be represented by 4-bits.
There are 256 possible values (or characters) in 8 bits.

A 128-bit encryption key can represent a total of (2^{128}) possible combinations. In terms of characters, if we consider using hexadecimal representation (where each character represents 4 bits), a 128-bit key would be represented by 32 hexadecimal characters. If using Base64 encoding, it would require 22 characters. The specific number of characters depends on the encoding method used.
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.
I have this same question and don't know it, please answer.

If the characters are 8 bits then you have 4 for them in 32 bits. ASCII is an 7 bit character set but in most programming languages a char is 8 bits.

only uses one byte (8 bits) to encode English characters uses two bytes (16 bits) to encode the most commonly used characters. uses four bytes (32 bits) to encode the characters.
