Explanation:
Detailed explanation-1: -AND gate with one input simply means that all inputs are shorted together. If the AND gate has two inputs then it will function according to above truth table (only the yellow squared one inputs are eligible).
Detailed explanation-2: -The output of OR gate is 1:-(A) If either one or both inputs are 1.
Detailed explanation-3: -Most logic gates have two inputs and one output.
Detailed explanation-4: -Sometimes you need to AND more than two inputs together. In fact, 3-and 4-input AND gates are just as common as the dual-input variety.
