Theoretically, 64. However, it is rare that 6 bit character sets would be used. Bytes are 8 bit and is the most popular form of information interchange today.
2^6
45 in binary is 101101, so you need at least 6 bits to represent 45 characters.
There are 256 possible values (or characters) in 8 bits.
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.
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.
Each hexidecimal character represents 4 bits, therefore 256 bits takes 256 / 4 = 64 characters.
128
2 bits equal 25 cents. So 6 bits would be 75 cents.
6 bits
6 characters
A bit is 1/8 of a dollar or 12.5 cents so if you have six bits it is 75¢
26 = 64
