Ans. The different number systems used in data representation are binary, octal, and hexadecimal. These number systems are commonly used in computer science to represent data in a more compact and efficient manner.
| 3. How do you convert a binary number to a decimal number for the SSC CGL exam? | |
Ans. To convert a binary number to a decimal number, you can use the positional system of binary numbers. Each digit in a binary number represents a power of 2, starting from 2^0 on the rightmost digit. Multiply each digit by 2 raised to the power of its position and sum the results to get the decimal equivalent.
| 4. Why is hexadecimal number system preferred over binary and octal in data representation for the SSC CGL exam? | |
Ans. The hexadecimal number system is preferred over binary and octal in data representation because it is more compact and easier to read and write. Hexadecimal numbers can represent a larger range of values in a shorter format compared to binary and octal numbers.
| 5. How can knowledge of data representation and number systems help in solving problems in the SSC CGL exam? | |
Ans. Knowledge of data representation and number systems can help in solving problems in the SSC CGL exam by enabling candidates to efficiently manipulate and convert data in different number systems. This understanding is crucial for answering questions related to computer science and quantitative aptitude sections of the exam.
