Modern processors today utilize when fetching instructions as a means of predicting where the branch will go and even begin executing before they have determined whether this is correct.

Speculative prediction

Explanation: Speculative prediction is the prediction method which can be optimizing in nature.This method usually runs in such a way that can lead ahead of time by predicting the next step or it's result.

This technique is also known as the dynamic execution which is usually found in the CPU devices and some other modern processing devices.Speculation prediction and execution works even when there is no necessity of the knowing about the next instruction.The result appearing can be correct or incorrect.
