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

16 of them.
8 bits = 64 character
In theory, 3 bits are enough to represent up to 8 (23) combinations.In theory, 3 bits are enough to represent up to 8 (23) combinations.In theory, 3 bits are enough to represent up to 8 (23) combinations.In theory, 3 bits are enough to represent up to 8 (23) combinations.
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.
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.
