Bypass capacitors and decoupling capacitors are one in the same in my
mind. It is just a different choice of words to describe the same part.
The function of a bypass (or decoupling) capacitor is to provide a low
impedance path from the power net to the ground or reference net in a
power distribution system and to provide a reservoir of charge to
service fast current demands by the circuit's current consumers. I
typically call the parts decoupling capacitors ('decaps' for short), but
you may see them equivalently referred to as bypass capacitors as well.
