Detailed explanation-1: -We can count the number of zeros and ones to see how many bits are used to represent 48 in binary i.e. 110000. Therefore, we have used 6 bits to represent 48 in binary.
Detailed explanation-2: -∴ 110000 is the binary form of the number 48.
Detailed explanation-3: -49 in binary is 110001. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits). We have used 6 bits to represent 49 in binary.
Detailed explanation-4: -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.
