Bitwise Masks

What does the AND bitwise operator do?

• Compares 2 bits and returns 1 if both are 1, otherwise returns 0

• Shifts all bits to the left by one position

• Inverts all the bits in a byte

• Compares 2 bits and returns 1 if either of them is 1

What is the result of a SHIFT RIGHT operation?

• Inverts the bits

• Equivalent of dividing by 2

• Discards the leftmost bit and adds a 0 on the left

• Equivalent of multiplying by 2

How can you reset bits to 0 using bitwise operators?

• Using the SHIFT LEFT operator

• Using the AND operator with a suitable mask

• Using the XOR operator with a suitable mask

• Using the OR operator with a suitable mask

What is the purpose of using masks in bitwise operations?

• To test or alter specific bits in a piece of data

• To multiply numbers

• To add two numbers

• To invert all bits

What does the XOR bitwise operator do?

• Returns 1 if both bits are 1

• Returns 1 if both bits are different

• Shifts all bits to the right

• Inverts the least significant bit

What is the result of the OR bitwise operation 10001000 | 11000001?

• 10001001

• 11001000

• 10000000

• 11001001

How do you turn on a specific bit using bitwise operations?

• Using the SHIFT RIGHT operator

• Using the COMPLEMENT operator

• Using the AND operator with a mask

• Using the OR operator with a suitable mask

What is the effect of the SHIFT LEFT operation on a number?

• Subtracts 1 from the number

• Divides the number by 2

• Adds 1 to the number

• Multiplies the number by 2

What does the COMPLEMENT bitwise operator do?

• Shifts all bits to the left

• Sets all bits to 0

• Inverts all the bits

• Adds 1 to each bit

How can you test a specific bit using bitwise operators?

• Using the XOR operator with a mask

• Using the AND operator with a suitable mask

• Using the OR operator with a mask

• Using the SHIFT RIGHT operator with a mask
