Logic and Shift Operations Quiz

True or False: The AND instruction performs a bitwise AND between two operands and stores the result in the source operand.

• True

• False

True or False: The NOT instruction inverts each bit of the operand.

• True

• False

True or False: In a logical shift left operation, the bits shifted out are replaced by zeros on the right.

• True

• False

True or False: The XOR instruction sets a bit to 1 if the bits in the operands are identical.

• True

• False

True or False: Arithmetic right shifts replicate the sign bit into the empty bit positions.

• True

• False

True or False: The OR instruction performs a bitwise AND between the operands.

• True

• False

True or False: A rotate operation, such as ROL, wraps bits around instead of discarding them.

• True

• False

True or False: The TEST instruction performs a bitwise AND between two operands and affects the status flags without altering the operands.

• True

• False

True or False: Logical shifts can be used to isolate specific fields within a binary word.

• True

• False

True or False: The SHR instruction shifts the operand left, inserting 0s into the lower bits.

• True

• False
