Multicore processors are computer chips that contain two or more processing units, called cores, on a single die. Each core can independently execute tasks, allowing for better performance and efficiency compared to single-core processors. This design enables computers to handle multiple applications simultaneously, improving multitasking capabilities. The use of multicore processors is common in modern devices, including laptops, desktops, and smartphones. They are essential for running complex software, such as video games and graphic design programs, as they can distribute workloads across multiple cores, leading to faster processing and smoother user experiences.
