What is a NAND gate?

What is NAND Gate? Give its truth table and logic circuit.

What is AND gate? Draw the symbol of AND gate and perpare its truth table.

What is a NOR Gate? Give its truth table.

A NOR gate and a NAND gate are connected as shown in the figure. Two different sets of inputs are given to this set up. 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

An OR gate is operated by using positve logic. What role will the OR gate play if we use negative logic? Or, Show that, the truth table of an OR gate in negative logic is similar to that of an AND gate in positive logic.

What is NOR gate? Prepare its truth table. Why is it called universal gate?

What is NOR gate? Prepare its Truth Table. Why is it called Universal gate?

If two inputs of a NAND gate are joined, what type of a gate is formed?

If A and B are the two inputs of an NAND gate, then the output will be

If the output of an OR gate is used as two inputs of a NAND gate, name the gate of the combination so formed.
