Binary:

NOT

This operation produces an output that is opposite to the input. i.e if the input is 1 (Logic True) then the output is 0 (Logic False). If the input is 0 (Logic False) then the output is 1 (Logic True)

The shorthand way of writing this is Q = NOT A where 'A' is the input and 'Q' is the output.It does not have to be A and Q, you could use any letter, but Q is a popular choice to describe a logic output.

AND:

This operation acts upon at least two inputs, say A, B to produce a single output Q.

In english, the rule is "If both A and B are True then the output is also True, otherwise its false

The shorthand for this is Q = A AND B

OR:

Again, this needs at least two inputs A, B to produce a single output.

In english the rule is "If either or both A, B are True then the output is also True.

The shorthand for this is Q = A OR B
