Serial processing: eating one M&M at a time until you have no M&Ms left and you feel kind of sick. Parallel processing: having 5 friends eat one M&M each, then repeating until there are none left. The bag empties 5 times faster because you are eating in parallel. Five threads.
As the name of both implies: * Serial processing: you take a list of items and do whatever you want to do with them one by one. It will take as long to complete the task as there are items in your list. Parallel processing: you have means of dividing your task among 2 or more processing units, processor cores for example, so the task will take (ideally) as long as #_of_items/#_of_processing_units to complete.
