Why buffer amplifiers are used if its gain is 1?
A buffer amplifier of unity gain is generally used when you need to islolate the source.Connecting a source to an amplifier, can have an affect on the original signal. A buffer amplifier stops the signal being affected by the subsequent amplifier sections. The input to the buffer is matched to the signal impedance.

Is a buffer amplifier equivalent to a a one input And gate or or a one input OR gate?
No. In the general case, a buffer amplifier is an analog device, but an AND or an OR gate is a digital device. Even in the specific case of a digital buffer amplifier, its still not the same because the digital buffer amplifier has more power available in its output circuit, giving it a higher fanout than just an ordinary AND or OR gate.

What is buffer amplifier and its applications?
A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.
What is buffer action in digital electronics?
noninverting, increased current drive.
What component is used as an amplifier?
