Multicore processing refers to the use of multiple processing units, or cores, within a single computer chip. Each core can independently execute tasks, allowing for better performance and efficiency. This means that a multicore processor can handle several operations simultaneously, making it ideal for running complex applications and multitasking. By distributing workloads across different cores, multicore processors can significantly speed up computing tasks. For example, when running software that supports parallel processing, such as video editing or gaming, users can experience smoother performance and faster results. This technology is now common in many laptops and desktops.
