A dual-core processor is a type of computer chip that contains two separate processing units, or cores, on a single piece of silicon. This design allows the processor to handle multiple tasks simultaneously, improving overall performance and efficiency. Each core can execute its own instructions, which means that dual-core processors can manage more operations at once compared to single-core processors. Dual-core technology is commonly found in various devices, including laptops, desktops, and smartphones. By utilizing two cores, these devices can run applications more smoothly, enhance multitasking capabilities, and provide a better user experience, especially when running demanding software or games.
