This answer is not simple amplifier if the gain is unlimited will tend to oscillate at higherfrequency usually there is a pin out for some amplifiers whereby adding a snub or capacitor will limit this gain internally so it can be stabilized. There is recommended techniques by not a guaranty of stability it depends on the amplifier bandwidth factor Q and grounds and other factors.
The gain of an op amp varies with frequency. After an op amp reaches the half-power point, the gain falls appreciably. And then once it hits the transition frequency, the op amp no longer provides any gain.
because it helps in noise reduction,bandwidth maximization
Power Supply Pins: Op-amps require power to operate. They have positive and negative power supply pins (+V and -V) that provide the necessary power levels for the op-amp to function. Output Pin: The output pin provides the amplified or manipulated signal based on the inputs. It's where the result of the op-amp's operation is obtained. Offset Null or Offset Adjustment Pins: Some op-amps have offset null pins that can be used to adjust the output offset voltage. This is useful for minimizing any unwanted voltage offset in the output. Frequency Compensation Pins: In some op-amps, additional pins are used for frequency compensation to ensure stable operation in high-frequency applications. Balance or Trim Pins: These pins are used in op-amps that are intended to be used in bridge or differential amplifier configurations, where precise balance between inputs is necessary.
When the magnitude of Vcc and Vee of op-amp are different the op-amp produces waveforms equal in the size of each rail.
The wording are confusing an op-amp is an op-amp a comparator is another animal. an op-amp can be used as square wave generator by overdriving it but the results are not desirable. However a comparator will be a switch on-off at the set level.

the op amp is a one IC which does not work at hige volteg so the IC not consumed the high frequncy

Drift in op amps refers to changes in the output voltage or other characteristics over time or due to environmental factors like temperature. It can affect the precision and stability of the op amp's operation, making it important to consider when designing circuits for high accuracy applications. Techniques such as using precision op amps or implementing compensation measures can help minimize drift effects.
A basic, single transistor amplifier differs from an op amp: 1. The op amp has more gain 2. The op amp may have higher input resistance (so it loads the circuit less) 3. The op amp may have a lower output resistance (so it can drive larger currents) 4. The op amp likely has a lower frequency response (due to the high gain, unless you provide some sort of feedback loop) 5. The op amp is ridiculously complex compared to a simple amplifier 6. The op amp will require a positive and negative voltage (may be unnecessary with a single transistor amplifier)

If an inline capacitor is inserted in the feedback from the output to the input of an op-amp it will act as a frequency filter and only boost audio frequencies within the resonant frequency range of the capacitor. If you gang multiple op-amps in a wein bridge arrangement you get an analogue audio filter capable of shelf boost or cut.
no, there can be many differences, the main one being the frequency capabilities. check their respective datasheets.
Supply voltage , temperature , frequency are factors that effect the electrical parameters of opamp
op-amp rolloff is an inherent low pass filter built into op-amp chips. Because op-amps have such a high gain, they are prone to breaking into high-frequency oscillation; therefore limiting the gain by frequency with a built in low pass filter helps stop this from happening. Imagine a super small signal is leaking into an op amp, because of the high gain it becomes no longer negligible and we have a high frequency signal when the output should be zero. The low pass filter lowers the gain at these High frequencies. Now, this will naturally create gain limits when designing circuits, forcing an upper bandwidth. This is adjusted for by lowering the gain you design into your circuit for the bandwidth you are dealing with (which is one of many reasons we build multi-stage amplifiers)
