Padding is a general term used to refer adding more bits

e.g.
you have some logic which take one vector of 8 bits as input and does some processing, but actually you are having a vector of only 6 bits to give as a input.

So you can add two extra bit(this is padding) to make it 8 bit vector.


Unpadding is exactly opposite of padding.

zero padding is adding zero's.

In many digital communication/serial protocol padding/ unpadding is done.
