How does multicore differ from a classic multiprocessing environment? Solution Multicore is differ from Multi processing because A multiprocessor systems having more than one central processing unit and allowing them to work in parallel. This is known as Simultaneous Multiprocessing. A multicore central processing unit has many execution cores on one CPU it means different things depending on the correct design but basically it means that a definite subset of the CPU\'s components is duplicate so multiple cores can work in parallel on separate operations. This is known as Chip level Multiprocessing..
