Answer (1)
Answer:Rejumble (Rearrange the jumbled letters):1. BERNUM → NUMBER2. STSME Y → SYSTEMS3. NA R B I → BINARY4. T A L → OCTAL5. MA L I C E → DECIMAL6. DECIHEXAMA L → HEXADECIMAL---Task Questions and Answers:1. What is a Binary Number System?It is a number system that uses only two digits: 0 and 1.2. What is the Octal Number System?It is a number system that uses eight digits (0 to 7).3. What is the Decimal Number System?It is the standard number system we use daily, using ten digits (0 to 9).4. What is a Hexadecimal Number System?It is a number system with sixteen symbols: 0–9 and A–F (where A=10 to F=15).5. Which number system uses letters?Hexadecimal uses letters A to F.6. Why is the binary number system used in computers?Because computers understand only two states: ON and OFF, which can be represented by 1 and 0.7. How many unique digits does the decimal number system use to represent all the numbers?It uses 10 digits (0–9).8. What is the purpose of using different number systems in computers?Different systems are used for efficiency in computing, data representation, and ease of human understanding (like hexadecimal for compact code).
