Q1. What is the binary representation of decimal 65, which corresponds to the ASCII character 'A'?

🔹 A. 1000001

🔹 B. 100001

🔹 C. 10000001

🔹 D. 1000010

💡 Difficulty: easy | ✅ Correct: A

Q2. Why was the original ASCII code defined using 7 bits instead of 8?

🔹 A. To allow for 128 distinct symbols including control characters

🔹 B. To match the size of a standard byte

🔹 C. To simplify error detection

🔹 D. To reduce power consumption

💡 Difficulty: medium | ✅ Correct: A

Q3. Why is two’s‑complement representation generally not used for ASCII characters, and what would happen if an ASCII byte were interpreted as a signed number?

🔹 A. ASCII includes non‑numeric symbols that need unsigned codes; interpreting as signed could yield negative values

🔹 B. Two’s‑complement saves memory; ASCII needs more bits

🔹 C. Two’s‑complement is only for floating‑point

🔹 D. ASCII CHARACTERS ARE ALWAYS POSITIVE

💡 Difficulty: hard | ✅ Correct: A
