Multi-core processors are computer chips that contain two or more processing units, known as cores, on a single chip. 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 multi-core processors is common in modern devices, including laptops, desktops, and smartphones. They are particularly beneficial for running complex software, such as video editing programs and gaming applications, which require significant processing power. Overall, multi-core technology enhances the speed and responsiveness of computing devices.
