Which of the following is true?

A Boolean data type has only two values: true and false

A Boolean data type has only two values: yes and no

A Boolean data type has only two values: 1 and 0

What is the purpose of logic gates?

To allow an electronic system to make a decision based on its inputs

To allow a program to make a decision based on its inputs

To allow an electronic system to make a decision based on its outputs

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

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

x > y will give the result true when the value of x is greater than the value of y

x > y will give the result false when the value of x is greater than the value of y

x > y will give the result true when the value of x is less than the value of y
