Answer 2

" These are perfect answers to the given statements ".

Explanation:

A)  In decimal number system, each position of weight is a power of  2.

This statement is False. Because, Decimal numbers are 'base 10' numbers, therefore the weight of each digit is a power of 10. Each digit has a position number.

B)  Binary numbers are very easy to remember as compare to its hexadecimal equivalent

This statement is False. Because, four digits in a binary number can be represented with a single hexadecimal digit. This creates very easy conversion between binary and hexadecimal numbers.

C) The digital computer works on binary numbers.

Option c is True. The digital computers are refer to modern computers which calculate numbers in binary. Binary refers to a numerical system consisting of zeros and ones.

D)There are more digits in octal number system than decimal number system.

This statement is False. Because,The octal numeral system, for short is the base 8 number system, but decimal number system has 10 digits.

E) We cannot modify or convert a hexadecimal  to a decimal number.

This statement is False. normally, we can modify a hexadecimal to a decimal manually, you must start by multiplying the hex number by 16. after that we can raise it to a power of 0 and increase that power by 1 each time according to the hexadecimal number equivalent.

F)  All modern computers should be use 32 or 64 bit words.​

This is True statement . If we are running windows on a computer less than 10 years old, our chip is almost guaranteed to be 64 bit and 32 bit.
