How do OR and XOR logic gates differ?
An OR gate always outputs 0 no matter what the inputs whereas an XOR outputs a 1 if one or more of the inputs is a 1
There is no difference
An OR gate outputs a 1 if one or more of the inputs is a 1 whilst an XOR outputs a 1 if only one (not both) of the inputs is a 1
Which of the following are logic gates?
