What is the most commonly used number system in computers?
The most commonly used Number system is the decimal positional number system, the decimal referring to the use of 10 numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 to construct all the required numbers. This was a discovery by the Indians. There are other two common number systems which are used in computers and computing science.
How many possible numbers are there in the binary system?
In the binary system, there can be only two choices for this number — either a “0” or a “1”. In the octal system, there can be eight possibilities: “0”, “1”, “2”, “3”, “4”, “5”, “6”, “7”. In the decimal system, there are ten different numbers that can enter the digit box:
Which number system is used to represent natural numbers?
Base 1 number system is called the unary numeral system and is the simplest numeral system to represent natural numbers. What is the equivalent binary number for the decimal number 43? To find the equivalent binary number, we need to divide 43 by 2, until we get 0 as the result.
