We are required to do only 4 parts of a question.
13. The least significant digit is the leftmost digit in any number. In hex we start with 16^0 at the leftmost digit(least significant) and increment the power by 1 as we move to the right. Hence the power of base in least significant digit is 0.
14. In a CPU, a parity bit is used for checking and correction of error.
15. Decimal number uses 10 as its base not 9. Hence the statement is FALSE.
18. CPU is made up of thousands of electric components are used and we can only communicate with them by turning the current on or off. And we have 1 for on and 0 for 0. Hence we use binary for computation in a computer.
20. In Binary we convert the number in a series of 0s and 1s which require higher numbers of bits to represent. For example for representing 5 in Binary we have 0101, hence the statement is FALSE.
