Understanding Logic Gates

What is a logic gate?

• A logic gate is a type of computer software that manages data storage.

• A logic gate is a physical structure used for building houses.

• A logic gate is a mathematical equation used to solve problems.

• A logic gate is an electronic device that performs a basic logical function on one or more binary inputs to produce a single binary output.

Name the basic types of logic gates.

• TRUE, FALSE, MAYBE

• ADD, SUBTRACT, MULTIPLY

• INPUT, OUTPUT, PROCESS

• AND, OR, NOT, NAND, NOR, XOR, XNOR

What is the function of an AND gate?

• The function of an AND gate is to output true regardless of the input values.

• The function of an AND gate is to output false only when all inputs are false.

• The function of an AND gate is to output true when at least one input is true.

• The function of an AND gate is to output true only when all inputs are true.

How does an OR gate operate?

• An OR gate outputs true if at least one input is true.

• An OR gate outputs false if at least one input is true.

• An OR gate outputs true only if both inputs are true.

• An OR gate outputs true only when all inputs are false.

What is the output of a NOT gate when the input is true?

• null

• false

• undefined

• true

Explain the function of a NAND gate.

• A NAND gate outputs false unless at least one input is true.

• A NAND gate outputs true unless all its inputs are true.

• A NAND gate outputs true only when all its inputs are true.

• A NAND gate has no effect on its inputs.

What is the difference between a NOR gate and an OR gate?

• A NOR gate is the negation of an OR gate; it outputs true only when all inputs are false.

• A NOR gate outputs true when at least one input is true.

• A NOR gate is the same as an AND gate, outputting true when all inputs are true.

• An OR gate outputs false only when all inputs are true.

How can logic gates be used in digital circuits?

• Logic gates are used to store data in memory.

• Logic gates are used to perform logical operations and build complex digital circuits.

• Logic gates can only perform arithmetic operations.

• Logic gates are exclusively used in analog circuits.

What is a truth table?

• A truth table is a diagram used to represent geometric shapes.

• A truth table is a method for solving algebraic equations.

• A truth table is a type of computer programming language.

• A truth table is a table that shows all possible truth values for logical expressions.

How do you represent a logic gate in a circuit diagram?

• Logic gates are represented by standardized symbols in circuit diagrams.

• Logic gates are represented by text labels in circuit diagrams.

• Logic gates are represented by colors in circuit diagrams.

• Logic gates are represented by numbers in circuit diagrams.
