There are 256 possible values (or characters) in 8 bits.

To represent 64 characters, you would need 6 bits. This is because 2^6 equals 64, meaning six bits can encode 64 different values, sufficient for each character. Each bit can represent two states (0 or 1), and with six bits, you can create combinations to represent all 64 characters.
45 in binary is 101101, so you need at least 6 bits to represent 45 characters.
Binary bits are necessary to represent 748 different numbers in the sense that binary bits are represented in digital wave form. Binary bits also have an exponent of one.
A "byte" is 8 bits, sufficient to represent a single character, such as the letter 'A'. A megabyte is 1 million bits, that's 1,000,000 single characters. A Gigabyte is 1 thousand megabytes, that's 1,000,000,000 single characters. 320 GB is therefore 320,000,000,000 single characters.
8 bits if unsigned, 9 bits if signed
23 can be represented in binary as 10111 and would therefore require 5 bits to represent.

To determine the minimum number of bits needed to store 100 letters and symbols, we first need to consider the total number of unique characters. Assuming we use the standard ASCII set, which includes 128 characters (letters, digits, and symbols), we can represent each character with 7 bits. Therefore, to store 100 characters, we would need a minimum of 700 bits (100 characters × 7 bits per character). However, if a larger character set like UTF-8 is used, it may require more bits for some characters.
8 bits = 64 character
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.
Most modern digital cameras use 24 bits (8 bits per primary) to represent a color. But more or less can be used, depending on the quality desired. Many early computer graphics cards used only 4 bits to represent a color.
