Definition - What does Dual Core mean?
Dual core is a CPU that has two distinct processors that work simultaneously in the same integrated circuit. This type of processor can function as efficiently as a single processor but can perform operations up to twice as quickly. Because each core has its own cache, the operating system is able to handle most tasks in parallel.
Techopedia explains Dual Core
While a dual-core system has twice the processing power of a machine with a single processor, this doesn't mean it will always perform twice as fast. This is because some operating systems and programs are not optimized for multiprocessing.
