Detailed explanation-1: -How Many Bits Does 24 in Binary Have? We can count the number of zeros and ones to see how many bits are used to represent 24 in binary i.e. 11000. Therefore, we have used 5 bits to represent 24 in binary.
Detailed explanation-2: -When looking for the number of bits needed to represent a given number of characters (letters, numbers, or symbols), you need to look at the powers of 2. For example, the reason that 5 bits are required to represent 27 characters is that 2^2=4 (4 is not enough), 2^3 is 8 (still not enough)… 2^5 is 32.
Detailed explanation-3: -Whole numbers (integers) are usually represented with 4 bytes, or 32 bits. In the past, symbols (e.g., letters, digits) were represented with one byte (8 bits), with each symbol being mapped to a number between 0-255.
