Explanation

Logic gates process binary signals (0 or 1). AND: output 1 only if both inputs are 1. OR: output 1 if any input is 1. NOT: inverts input.

NAND (NOT AND): opposite of AND – output 0 only if both inputs are 1. NOR (NOT OR): opposite of OR. XOR: output 1 if inputs are different.

Truth tables show all input/output combinations. Complex circuits combine gates. NAND gates alone can create any logic function – called a universal gate.
