Originally such an amplifier did mathematical functions.
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .

Operational amplifiers are usually bought as an I.C., but they may be constructed with discrete components too.
Differential amplifier ANSWER: A differential amplifier is an op amp. If any amplification is required a preamplifier is used mainly to cut the white noise and improve the input impedance

design and implementation of a buffer circuit using operational amplifier
The LM358 is an operational amplifier.
It has several but one of the main ones is that it has built in frequency compensation, which its predecessor the 709 operational amplifier did not.

Op amps stands for operational amplifier. An operational amplifiers is a high gain voltage amplifier that requires a differential input and produces single outputs.
