Detailed explanation-1: -OR gate-output is 1 if AT LEAST one input is 1. XOR gate-output is 1 if ONLY one input is 1. NAND gate-output is 1 if AT LEAST one input is 0. NOR gate-output is 1 if BOTH inputs are 0.
Detailed explanation-2: -Like the AND gate, the OR function can hold any number of individual inputs. However, commercially available OR gates are available in 2, 3, or 4 input types.
Detailed explanation-3: -Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.
Detailed explanation-4: -When both inputs are equal, either are 1 or both are 0, the output will be logical 0. This is the reason an XOR gate is also called an anti-coincidence gate or inequality detector. This gate is called XOR or exclusive OR gate because its output is only 1 when its input is exclusively 1.
