Q

What is an AND logic gate?

A

Both the inputs needs to be the same for the outcome to be the same:
True + true = true
true + false = false
false + false = false
false + true = false
if this was a statement, both parts would have to be true
e.g. I have blonde hair and blue eyes

Q

What is the NOT logic gate?

A

The NOT logic gate is always the opposite output to what the input was
True = false
False = true
An example of this is saying something is not something else or think of it as it is NOT true therefore it is false and it is NOT false therefore it is true

Q

What is the XOR logic gate?

A

The XOR logic gate is very similar to the OR logic gate and in most cases, only one of the inputs has to be true for the outcome to be true:
True + false = true
False + true = true
False + false = false

The only difference is that when both the inputs are true then the outcome will be false
true + true = false
