Etymology

buff +‎ -er

This definition is lacking an etymology or has an incomplete etymology. You can help Wiktionary by giving it a proper etymology. A buffer in Electronics is nothing but a circuit designed to meet the impedance matching. This means a circuital module, in order to be connected to other circuital module, both having different impedance is achieved by buffer. Suppose two pieces of pipes both of different diameters are connected the water never flows smooth from one pipe to other. The same happens with the circuit modules having different impedance. It results in attenuation to a great extent causing power lossses and distortions. Hence we go for buffering. Here to the output of a high impedance module an impedance matched input side of buffer circuit is connected. within the circuit the impedance is brought down and the output of the buffer which is small is used to connect to the input of a low impedance module( any circuit).

    • 2011 November 10, Jeremy Wilson, “England Under 21 5 Iceland Under 21 0: match report”, Telegraph:

      An utterly emphatic 5-0 victory was ultimately capped by two wonder strikes in the last two minutes from Aston Villa midfielder Gary Gardner. Before that, England had utterly dominated to take another purposeful stride towards the 2013 European Championship in Israel. They have already established a five-point buffer at the top of Group Eight.
