Sample Tamil Nadu HSE First Year Computer Science Practice Questions

Try these sample questions to review concepts for the Tamil Nadu HSE First Year Computer Science exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which number system uses only the digits 0 and 1?
A.Decimal
B.Binary
C.Octal
D.Hexadecimal
Explanation: Binary (base 2) uses only digits 0 and 1. It is the native representation used by digital computers.
2What is the decimal equivalent of the binary number 1011₂?
A.9
B.10
C.11
D.13
Explanation: 1×2³ + 0×2² + 1×2¹ + 1×2⁰ = 8 + 0 + 2 + 1 = 11.
3How many unique symbols (digits) does the hexadecimal number system use?
A.8
B.10
C.16
D.2
Explanation: Hexadecimal is base 16, so it uses 16 symbols: 0–9 and A–F.
4What is the octal equivalent of decimal 10?
A.10₈
B.12₈
C.11₈
D.8₈
Explanation: 10 ÷ 8 gives quotient 1 and remainder 2; writing remainders as digits yields 12₈. Check: 1×8 + 2 = 10₁₀.
5Which binary value equals hexadecimal A₁₆?
A.1001₂
B.1010₂
C.1100₂
D.1111₂
Explanation: A₁₆ = 10₁₀ = 8+2 = 1010₂. Each hex digit maps to 4 binary bits.
6What is 1’s complement of the 8-bit binary number 01011010?
A.10100101
B.10100110
C.01011010
D.11011010
Explanation: 1’s complement flips every bit: 0↔1, so 01011010 becomes 10100101.
72’s complement of an n-bit number is obtained by:
A.Inverting all bits only
B.Inverting all bits and adding 1
C.Adding 1 then inverting bits
D.Reversing the bit order
Explanation: 2’s complement = 1’s complement + 1 (invert all bits, then add 1). It is the standard signed integer representation in computers.
8Convert binary 1101₂ to decimal using place values.
A.11
B.12
C.13
D.14
Explanation: Expand place values 8, 4, 2, 1 for bits 1,1,0,1: 8+4+0+1 = 13 in decimal.
9In positional notation, the weight of the rightmost digit in base b is always:
A.b
B.0
C.b⁰ = 1
D.bⁿ
Explanation: The least significant digit has weight b⁰ = 1 in any base b.
10What is the binary equivalent of decimal 25?
A.11001₂
B.11010₂
C.10101₂
D.11101₂
Explanation: 25 = 16+8+1, which are 2⁴, 2³, and 2⁰, so the binary bits are 11001₂.

Tamil Nadu HSE First Year Computer Science: Suggested Study Strategy

1Study from the current SCERT / Samacheer Kalvi Class 11 Computer Science textbooks and the year's model question paper pattern released for DGE public exams.
2Practise both conceptual MCQs and the official long/short answer formats; this bank cannot replace writing or practical skill evidence.
3Hand-trace every Python snippet (range bounds, indentation, list mutation vs string immutability) before looking at the explanation.
4Drill number-system conversions and Boolean truth tables until they are automatic.
5Use the official timetable to plan revision around your specific sitting date if you are an arrear candidate.
6After each practice set, log weak topic areas (by unit) and re-read those textbook chapters before retesting.
