FAQs on Classification of Numbers & Divisibility Video Lecture - Quantitative Aptitude (Quant)

1. What are the different types of number systems?

Ans. The most common types of number systems include the decimal system (base 10), binary system (base 2), octal system (base 8), and hexadecimal system (base 16). Each system has its own set of symbols and rules for representation.

2. How do you convert a binary number to a decimal number?

Ans. To convert a binary number to a decimal number, you multiply each digit by 2 raised to the power of its position (starting from 0 on the right) and sum the results. For example, for the binary number 1011, the calculation would be: (1×2^3) + (0×2^2) + (1×2^1) + (1×2^0) = 8 + 0 + 2 + 1 = 11 in decimal.

3. What is the importance of number systems in computer science?

Ans. Number systems are crucial in computer science because they are used for data representation. Computers operate using binary (0s and 1s), and understanding different number systems helps in programming, data processing, and algorithm development.

4. How do you convert a decimal number to hexadecimal?

Ans. To convert a decimal number to hexadecimal, divide the decimal number by 16 and record the remainder. Repeat this process with the quotient until it equals zero. The hexadecimal number is then formed by the remainders read in reverse order. For example, to convert 255 to hexadecimal: 255 ÷ 16 = 15 remainder 15 (F), 15 ÷ 16 = 0 remainder 15 (F), so 255 in hexadecimal is FF.

5. What is the relationship between different number systems?

Ans. Different number systems can be converted into one another through specific mathematical processes. For example, binary can be converted to decimal, and from decimal to hexadecimal. Understanding these relationships is essential for tasks like programming and data manipulation in computing.
