FAQs on Introduction to Number System Video Lecture - Digital Electronics - Electronics and Communication Engineering (ECE)

1. What is the number system?
Ans. The number system is a way of representing and expressing numbers. It consists of a set of symbols or digits and rules for combining these symbols to represent different values. The most commonly used number systems are decimal, binary, octal, and hexadecimal.
2. What is the decimal number system?
Ans. The decimal number system is the most widely used number system. It uses ten different digits (0-9) to represent numbers. Each digit's position in a decimal number determines its value, and the base of the decimal system is 10. For example, the number 1234 in the decimal system represents 1 thousand, 2 hundreds, 3 tens, and 4 units.
3. What is the binary number system?
Ans. The binary number system is a base-2 number system that uses only two digits, 0 and 1, to represent numbers. It is widely used in computer systems because digital electronic devices can easily represent and manipulate binary digits. Each digit's position in a binary number represents a power of 2. For example, the binary number 1010 represents 1 eight, 0 fours, 1 two, and 0 ones, which is equivalent to the decimal number 10.
4. What is the octal number system?
Ans. The octal number system is a base-8 number system that uses eight different digits (0-7) to represent numbers. It is primarily used in computer programming, specifically in UNIX and Linux systems. Each digit's position in an octal number represents a power of 8. For example, the octal number 127 represents 1 sixty-four, 2 eights, and 7 ones, which is equivalent to the decimal number 87.
5. What is the hexadecimal number system?
Ans. The hexadecimal number system is a base-16 number system that uses sixteen different digits (0-9 and A-F) to represent numbers. It is commonly used in computer programming and digital electronics due to its compact representation of binary data. Each digit's position in a hexadecimal number represents a power of 16. For example, the hexadecimal number 1F represents 1 sixteen and 15 ones, which is equivalent to the decimal number 31.
