An AND gate is a logic gate that outputs a high signal only when all of its inputs are high.

• AND gate is a basic logic gate used in digital circuits.

• It has two or more inputs and one output.

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

• It follows the truth table: 0 AND 0 = 0, 0 AND 1 = 0, 1 AND 0 = 0, 1 AND 1 = 1.

• AND gates are commonly used in computer processors, memory units, and other digital systems.

A NOR gate is a logic gate that produces an output of true only when all of its inputs are false.

• NOR gate is a type of logic gate that performs the logical NOR operation.

• It has two or more inputs and one output.

• The output of a NOR gate is true (or high) only when all of its inputs are false (or low).

• It is the complement of the OR gate.

• The truth table for a NOR gate is: 0 NOR 0 = 1, 0 NOR 1 = 0, 1 NOR 0 = 0, 1 NOR 1 = 0.

• NOR gates are commonly used in digital circuits for vario...read more

A basic gate is a fundamental building block of digital circuits that performs a specific logical operation.

• Basic gates include AND, OR, NOT, NAND, NOR, and XOR gates.

• AND gate outputs true only when all inputs are true.

• OR gate outputs true when at least one input is true.

• NOT gate inverts the input signal.

• NAND gate outputs the negation of the AND gate.

• NOR gate outputs the negation of the OR gate.

• XOR gate outputs true when the number of true inputs is odd.
