In the given circuit,$A$ and $B$ are two inputs and $C$ is the output. Which logic gate does this circuit represent?

The logic gate equivalent to the combination of logic gates shown in the figure is

Find the values of $Y_1$ and $Y_2$ respectively in the following logic circuit if both $A$ and $B$ are $1$.

The output of a logic gate is low when any one of the inputs is high. Which gate does this statement describe?

The circuit diagram shows a combination of logic gates. When inputs $P$ and $Q$ change to state $0$ with inputs $R$ and $S$ still at state $1$,the states of outputs $X$,$Y$ and $Z$ change to:

If $A = 100101$ and $B = 110110$ are applied to $X-NOR$ gate,then the output will be
