An epoch is a measure of the number of times all of the training vectors are used once to update the weights.
For batch training all of the training samples pass through the learning algorithm simultaneously in one epoch before weights are updated.

For sequential training all of the weights are updated after each training vector is sequentially passed through the training algorithm.
