The AND instruction is used for supporting logical expressions by performing bitwise AND operation. The bitwise AND operation returns 1, if the matching bits from both the operands are 1, otherwise it returns 0. For example − The AND operation can be used for clearing one or more bits. For example, … See more The OR instruction is used for supporting logical expression by performing bitwise OR operation. The bitwise OR operator returns 1, if the matching bits from either or both operands are … See more The TEST instruction works same as the AND operation, but unlike AND instruction, it does not change the first operand.
