Card 1
Question: What is digital logic and what does it operate on?
Answer: Digital logic is the foundation of all modern computing and electronic devices. It operates on discrete, typically binary, values, meaning that signal
Card 2
Question: What is the mathematical system that governs binary operations called, and who developed it?
Answer: The mathematical system that governs these binary operations is known as Boolean algebra, named after George Boole, who first described it in the mid-
Card 3
Question: What are logic gates in digital logic?
Answer: Logic gates are electronic circuits that implement Boolean functions, taking one or more binary inputs and producing a single binary output based on a
Card 4
Question: How are TRUE and FALSE represented in digital systems and electronic circuits?
Answer: TRUE and FALSE correspond directly to the binary digits 1 and 0. In an electronic circuit, a high voltage level (e.g., +5 Volts) might represent a log
Card 5
Question: What is the function of a NOT gate?
Answer: The NOT gate, also called an inverter, inverts the input: if the input is 1, the output is 0, and vice versa.
Card 6
Question: What is the Boolean expression for a NOT gate?
Answer: Q = A' (or Q = NOT A, or Q = Ā)
Card 7
Question: What is the output of a NOT gate if the input is 0?
Answer: The output is 1.
Card 8
Question: Under what condition does an AND gate produce an output of 1?
Answer: The AND gate produces an output of 1 only if all its inputs are 1.
Card 9
Question: What is the Boolean expression for an AND gate?
Answer: Q = A · B (or Q = A AND B)
Card 10
Question: What is the output of a 2-input AND gate if inputs A=1 and B=0?
Answer: The output Q is 0.
