A ‘1’ means that current is present. For instance, if current is present at an output of a gate then this is represented as a ‘1’. Instead of placing a ‘1’ at the output other terms can be applied - high, true, on or up - all mean that current is present.

A ‘0’ means that current is not present. For instance, if current is not present at an output of a gate then this is represented as a ‘0’. Instead of placing a'0’ at the output other terms can be applied - low, false, off or low - all mean that current is not present.

Alternative ways of representing the AND gate are written below.

QUESTION:
Write the OR truth table using alternative terms other than ‘1s’ and ‘0s’.
