• The purpose of computer systems is to process data. Computers use electronic circuits, which act as switches that can be turned on or off, to accomplish this. We represent these two states in binary form: When a switch is off, it shows up as a 0. 1 indicates that the switch is on.
• In mathematics, the decimal system is a positional numeral system that uses 10 as its base and calls for the use of 10 different numerals, including 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. To represent decimal fractions, a dot (decimal point) is also necessary.
• The most significant digit is the one on the left (MSD). The least-significant digit is the one on the right (LSD).
• The quantity of distinct digits, including the digit zero, used to represent numbers in a positional numeral system is known as the radix or base. The decimal/denary system, for instance, has a radix of ten because it uses the ten digits from 0 to 9.
• Because the octal number system is a base-8 number system, any number in the octal system must be represented by 8 different symbols. The numbers are 0 through to seven.
• To get the binary equivalent of a decimal number, Start with the integer in question and divide it by 2 keeping track of the quotient and remainder to convert it to binary. Divide the quotient by 2 repeatedly until you reach zero. Then just write the remaining amounts out in reverse order.
• No, 129 is an example of a decimal number since 9 is not included in the octal numbers.
