,ICT2632 – Assignment 1 MCQ Answers
1. What is the basic building block of digital circuits?
✅ Answer: a) Transistor
Explanation: Transistors are the heart and soul of digital circuits. Think of them as tiny
electronic switches flipping on and off, making everything from calculators to
supercomputers work. Without them, we'd still be using abacuses—yikes!
2. In binary code, how many bits make up a byte?
✅ Answer: b) 8
Explanation: A byte is like a mini storage unit in the digital world, and it's made up of 8
bits. Why 8? Because that's how computers like it. It’s the digital version of “why is a pizza
cut into 8 slices?”—it just works!
3. Which logic gate performs the logical AND operation?
✅ Answer: d) AND gate
Explanation: The AND gate is like a strict teacher—both inputs must be 1 (true) for it to
output 1. If even one input is 0, no luck, you get a 0. No exceptions, no excuses!
4. What does the term "Boolean algebra" refer to in digital logic?
✅ Answer: c) Algebra with binary variables
Explanation: Boolean algebra deals with 1s and 0s, the bread and butter of computers.
It’s like regular algebra, but instead of numbers, we play with "true" and "false" values.
Geeky? Absolutely. Useful? 100%.
5. In a binary numbering system, what does each digit represent?
✅ Answer: b) Powers of 2
Explanation: Binary works in powers of 2, just like decimal works in powers of 10. So,
while you’re used to counting in tens (10, 100, 1000), computers count in twos (2, 4, 8, 16).
It’s like a toddler learning to count but only using two fingers.
6. What is the binary representation of the decimal number 13?
✅ Answer: a) 1101
Explanation: 13 in binary is calculated as 1×2³ + 1×2² + 0×2¹ + 1×2⁰ = 1101₂. Imagine
counting in a weird way, but hey, that's how computers roll.
, 7. In a half-adder circuit, what does XOR stand for?
✅ Answer: a) Exclusive OR
Explanation: XOR is like a picky bouncer—it only lets in one "1" at a time. If both
inputs are 1, the XOR gate says, "Nope, you’re not exclusive enough," and outputs 0.
8. What is the result of the logical AND operation for inputs A=1 and B=0?
✅ Answer: a) 0
Explanation: AND gates only output 1 when both inputs are 1. If one of them is 0, the
result is always 0. It’s like needing two keys to open a treasure chest—if one is missing, no
gold for you!
9. Which component is commonly used to store a single binary digit in digital
memory?
✅ Answer: a) Transistor
Explanation: Transistors don’t just switch signals; they also store bits of data. Without
them, your phone wouldn’t remember your Wi-Fi password, and we’d all be doomed.
10. What is the purpose of a multiplexer in digital circuits?
✅ Answer: b) Combines multiple signals into one
Explanation: A multiplexer (MUX) is like a traffic controller for data—choosing which
signal gets to pass through a single channel at any given time. Think of it as the guy deciding
which car gets on the freeway first.
11. How many bits make a nibble?
✅ Answer: a) 4
Explanation: A nibble is half a byte, or 4 bits. If a byte were a full pizza, a nibble would
be just two slices—still satisfying, but not the whole thing.
