1.What is Number System and its Types?
The number system is simply a system to represent or express numbers. There are various types of number systems and the most commonly used ones are decimal number system, binary number system, octal n umber system, and hexadecimal number system.
2. Why is the Number System Important?
The number system helps to represent numbers in a small symbol set. Computers, in general, use binary numbers 0 and 1 to keep the calculations simple and to keep the amount of necessary circuitry less, which results in the least amount of space, energy consumption and cost.
3. What is Base 1 Number System Called?
The base 1 number system is called the unary numeral system and is the simplest numeral system to represent natural numbers.
4. 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. Therefore, (43)10 = 1010112
5. How to convert 308 into a decimal number?
308 = (3 × 81) + (0 × 80) = 24
6. What is number system your answer?
A number system is defined as a system of writing to express numbers. It is the mathematical notation for representing numbers of a given set by using digits or other symbols in a consistent manner. It provides a unique representation of every number and represents the arithmetic and algebraic structure of the figures.
7. What is the importance of number system?
Number Systems is crucial for understanding the processing of digital system. Digital system takes binary, octal & hexadecimal number as input and process it and generates output.
