An $AND$ gate

The truth table for the given logic circuit is: (Inputs $A, B$ and Output $E$)

For a two-input logic gate, when the inputs are $0$ and $0$, the output is $1$. When the inputs are $1$ and $0$, the output is $0$. The type of logic gate is:

Sum of the two binary numbers $(100010)_2$ and $(11011)_2$ is

$A$ $NOR$ gate and a $NAND$ gate are connected as shown in the figure. Two different sets of inputs are given to this setup. In the first case, the inputs to the gates are $A=0, B=0, C=0$. In the second case, the inputs are $A=1, B=0, C=1$. The output $D$ in the first case and second case respectively are

If $ A=1 $ and $ B=0 $,then in terms of Boolean algebra,$ \bar{A}+B= $
