Logic Gates and Dual Core Processors Quiz

What condition must be met for the output of an AND gate to be true?

• Both inputs need to be on (true)

• Only one input needs to be on (true)

• Both inputs need to be off (false)

• The input is changed to the opposite

Which logic gate produces a true output if at least one input is true?

• OR gate

• AND gate

• NOT gate

• Dual core

What does a NOT gate do to its input?

• Changes the input to the opposite

• Requires both inputs to be true

• Requires one input to be true

• Multiplies the input by two

What does "dual core" mean in computing?

• It has 2 cores and can do 2 instructions at the same time

• It has 2 memory chips

• It can only do one instruction at a time

• It has 2 power supplies

If you want a logic gate to output true only when both inputs are true, which gate should you use?

• AND gate

• OR gate

• NOT gate

• Dual core

Explain how a dual core processor can improve computer performance compared to a single core processor.

• It can process two instructions at the same time, increasing efficiency.

• It uses less electricity.

• It stores more data.

• It makes the computer lighter.

What is the name of the logic gate shown in the diagram?

If input A is 1 and input B is 0, what will be the output Y of the OR gate?

• 0

• 1

• 2

• Cannot be determined
