A: difference in bias current causes the other
On a differential amplifier while there is some voltage offset there is also current offset which is dependent on the value of the F/B resistance the bigger value the more offset.

Output offset voltage is the output of an operational amplifier when the two inputs are shorted together (and often tied to ground). >> The output offset voltage (Voo) is caused by mismatching by two input terminals. Even though all the components are integrated on the same chip, it is not possible to have two transistors in the input differential amplifier stage with exactly the same characteristics. This means that the collector currents in these two transistors are not equal, which causes a differential output voltage from the first stage. The output of first stage is amplified by following stages and possibly aggravated by more mismatching between them. Thus the output voltage caused by mismatching between two input terminals is the output offset Voo .
They are both used for similar functions, such as oscillators, amplifiers, and switches. The vacuum tube was invented first, and has therefore been around longer than the transistor.

Voltage or current Offset is the voltage or current seen at the outputeven when no input is applied. This happens due to various reasons such as imbalance in the device, asymmetry and many more. So, offset adjustment means, providing the required input externally, so that the output voltage and current are zero.

The difference between and input force and an output force is that an output force is force exerted by a machine, and an input force is force exerted on a machine.
What_is_difference_between_microphone_and_voice_input
Input offset voltage is the equivalent voltage at the input of an operational amplifier. If an amplifier has a voltage gain of ten and an input offset voltage of 10 microvolts, a level of 100 microvolts will appear at the output with no input. Manufacturers try to design an op amp so the input offset voltage is as small as possible to minimize this error voltage at the output of the amplifier, especially for applications where small voltages are being amplified.

What is the difference between output and input?If you sing into a microphone you can hear the microphone's output.Sound coming out of the power amp to the speakers.That is the input of the loudspeaker.Do you see the difference?Your voice is the microphone's input. Its output is electrical impulses that are input to the amplifier. The amplified impulses are the output of the amplifier and input to the speaker. Sound waves are output of the speaker and input to your ears.

internal input is the one where we give inputs as well and external input is the clock input
